| |
| - | === Week 1 ===
| |
| - | ==== Tuesday 17 June 08 ====
| |
| - |
| |
| - | * Prepared competent JM109 cells using TSS method. 25 tubes of 0.2 ml were prepared, labelled 'iGEM 17-6-8 Jnn' where nn is a number from 01 to 25. These are in the pink box in Garry's -80°C freezer.
| |
| - |
| |
| - | ==== Thursday 19 June 08 ====
| |
| - |
| |
| - | * Eluted DNA for BioBrick E0240 (GFP) from square 1001, well 4B and used this to transform half of tube J25; other half was transformed with 1.5μl of J33207 (Edinbrick1) as a control to test the competence of the cells. Plated 100 microlitres of each to LA+amb+BW. Incubate at 37°C overnight.<br />
| |
| - | '''Plate 1:''' JM109 transformation with E0240 eluted DNA.<br />
| |
| - | '''Plate 2:''' JM109 transformation with J33207 plasmid DNA (control).
| |
| - |
| |
| - | ==== Friday 20 June 08 ====
| |
| - |
| |
| - | * '''Result of transformation:''' the positive control was highly successful, with hundreds of colonies, but no colonies were present on the plate transformed with the BioBrick DNA indicating some problem with the DNA elution. Need to check that we got the method right.
| |
| - | * Ordered primers for ''dxs'', ''appY'' and ''glgC''. There are no forbidden restriction sites in the first two, so primers with full prefix and partial suffix were ordered to clone as EcoRI-SpeI fragments, but ''glgC'' has two EcoRI sites which will have to be mutated out. We therefore had a choice of cloning it initially as a XbaI-PstI fragment, or attempting the BABEL system, and decided to try BABEL first. If it proves too unreliable, we will need to order new primers to clone it the old-fashioned way.<br />

| - | === Week 2 ===
| |
| - | ==== Tuesday 24 June ====
| |
| - |
| |
| - | * Sarah S wants to revive one of the BioBricks from the Registry (pBad+''gfp''), so we'll see whether she can get it to work.
| |
| - |
| |
| - | ==== Wednesday 25 June ====
| |
| - |
| |
| - | * Primers arrived. Made up 500μM stock solutions in EB and 10μM working solutions (f and r together) in water. Performed PCR with Kod, annealing at 55°C and extending for 38 seconds (expected sizes are: ''dxs'' 1862 + prefix and suffix; ''appY'' 749 + prefix and suffix; ''glgC'' 1295 with no prefix or suffix (except the extra TAA). Result: all looked good, nice pure bands.<br />
| |
| - | '''Gel 1:''' markers, empty lane, ''dxs'', ''appY'', ''glgC'', ''appY'' (repeat), ''glgC'' (repeat), markers.
| |
| - |
| |
| - | ==== Thursday 26 June 08 ====
| |
| - |
| |
| - | * Purified DNA from PCR reactions. Used 20 microlitres of glass beads and eluted to 40 microlitres of TE.<br />
| |
| - | '''Sample P1:''' ''dxs'' PCR product<br />
| |
| - | '''Sample P2:''' ''appY'' PCR product<br />
| |
| - | '''Sample P3:''' ''glgC'' PCR product<br />
| |
| - | * Set up digests to clone ''appY'' and ''dxs'' into Edinbrick1. Digests with 32μl water, 5μl buffer E, 4μl Edinbrick1 DNA, 4μl purified PCR product, 2.5μl SpeI, 2.5μl EcoRI. Incubated at 37°C. Purified. Set up ligations:<br />
| |
| - | '''Ligation L1:''' ''dsx'' + Edinbrick1, EcoRI/SpeI<br />
| |
| - | '''Ligation L2:''' ''appY'' + Edinbrick1, EcoRI/SpeI<br />
| |
| - | '''Ligation L3:''' ''glgC'' (5μl) \+linear Babel1 (16-2-8, 2μl) with PNK<br />
| |
| - | '''Ligation L4:''' ''glgC'' (5μl) \+linear Babel2 (18-2-8, 2μl) with PNK<br />

In each case, 100μl of cells were transformed with 5μl of ligation, and the remaining 5μl of each ligation was frozen so that it could be analysed if the transformations fail. Fresh Blue-White ampicillin plates were prepared.<br />

| - | * '''Result of transformations:'''<br />
| |
| - | '''Plate 3:''' 1 white; '''Plate 7:''' 5 white, 13 blue.<br />
| |
| - | '''Plate 4:''' no growth; '''Plate 8:''' no growth.<br />
| |
| - | '''Plate 5:''' 1 white; '''Plate 9:''' 3 white, 20 blue, possible signs of phage.<br />
| |
| - | '''Plate 6:''' maybe one tiny white; '''Plate 10:''' 7 white, 9 blue.<br />
| |
| - | The white colonies were transferred to fresh plates of the same medium:<br />
| |
| - | '''Plate 11:''' possible pSB1A2+''dxs'' transformants.<br />
| |
| - | '''Plate 12:''' possible Babel1+''glgC'' transformants.<br />
| |
| - | '''Plate 13:''' possible Babel2+''glgC'' transformants.<br />
| |
| - | The new plates were incubated at 37°C. The old plates were left at room temperature to see if any further colonies would appear.
| |

| |
| - | ==== Sunday 29 June 08 ====
| |
| - |
| |
| - | * Streaks on plate 12 show strong signs of phage infection and are unusable apart from the single white one from plate 5. At least one of the streaks on plate 13 also has a couple of plaques, but plate 11 looks fine. This suggests that phage may have come from the Babel DNA stock (or the PNK, which seems unlikely). Set up overnight cultures (2.5ml LB in 20ml bijoux) for minipreps. Numbers 1 to 6 are pSB1A2+''dxs'' from plate 11, all white, number 7 is from plate 12 (the white clone from plate 5), and 8 to 12 are from plate 13, white or pale blue. Incubated at 37°C with shaking.
| |
| - | * Also note: a couple more colonies turned up on plates 5 and 6. The one on 6 looks like an escape, but the one on 5 looks OK. Subbed them both to a fresh plate ('''Plate 14'''). Previous plates, apart from plates 4 and 8 which had no growth, were transferred to the cold storage room.
| |
| - |
| |
| - | === Week 3 ===
| |
| - | ==== Monday 30 June 08 ====
| |
| - |
| |
| - | * Plasmid DNA minipreps:<br />
| |
| - | '''M1 to M6:''' pSB1A2+''dxs'' white colonies<br />
| |
| - | '''M7:''' Babel1+''glgC'' white colony<br />
| |
| - | '''M8 to M12:''' Babel2+''glgC'' white and pale blue colonies<br />
| |
| - | Minipreps M1 to M6 were digested with EcoRI and PstI ('''Gel 2'''). The expected pattern is pSB1A2 vector band at 2.04kb (2079 bp less prefix and suffix) and ''dxs'' insert band around 1.9kb. M1 showed bands around 1.1kb and 2.1kb. M5 showed no DNA. The other four showed a vector-like band around 2kb and a fainter, fuzzier band around 3kb, possibly a 'ghost' band. Thus none of the clones show the expected pattern of bands (although it is conceivable, since the vector and insert bands are so close in size, that they may be lying on top of each other; ''dxs'' has an internal EcoRV site at +504 and two HindIII sites at +606 and +1230, whereas pSB1A2 lacks such sites so this could be used to check). In conjunction with the total lack of growth on the ''appY'' plates, this suggests that something went wrong in the cloning procedure. The next step is to run the remaining ligation material on a gel and see what it looks like.
| |
| - |
| |
| - | ==== Tuesday 1 July 2008 ====
| |
| - |
| |
| - | '''Gel 3:''' minipreps M2, M3, M4 and M6 (pSB1A2+''dxs'' clones) digested with EcoRI alone; lanes 5 and 6, 2.5μl of ligations L1 and L2. Result: all 4 minipreps now give a 4.2kb band (plus the same 3.2kb 'ghost' band as before) consistent with pSB1A2 carrying a 2kb insert. Would be nice to confirm identity using HindIII (2 internal sites). Both ligations show clear signs of insert and vector bands (oddly, the ''dxs'' insert band overlaps the pSB1A2 vector band whereas the ''appY'' insert band overlaps the ''lacZ'' insert excised from Edinbrick1). However, no ligated bands are visible. Thus the DNA purification is fine; if there was a a problem, it is with the ligase or ligase buffer.<br />
| |
| - | '''Gel 4:''' Minipreps M7 to M12 (supposed to be ''glgC'' in Babel vectors) digested with EcoRI and PstI to excise the inserts. M10 and M11 have a single 3kb band consistent with vector, but no insert band at 1.2kb. M7, M8, M9 and M12 all show a single band at about 2.4kb which is not consistent with Babel vectors if properly digested. Unless the digests totally failed, none of these plasmids would seem to contain ''glgC''.
| |
| - | * '''BUT WAIT:''' Turns out gel 4 has undigested plasmid DNA rather than the EcoRI/PstI digests. These were run on '''Gel 5'''. Since ''glgC'' is about 1295bp with internal EcoRI sites at +570 and +1067, we would expect to see a vector band at 3kb and the insert cut into bands of around 570bp, 567bp and 228bp. This is precisely what we see in the case of M10 and M11. We can therefore conclude that '''M10 and M11''' both represent the Babel2+''glgC'' BioBrick. This is not sufficient to determine the orientation, but a single EcoRI digest of these two clones should be sufficient to establish that. Even if both are in the reverse orientation, they can still be used as templates for the three mutagenesis step which will be required to produce the final BioBrick.
| |
| - | * Also attempted HindIII digests of M2, M3, M4 and M6 to confirm that the insert is really ''dxs'', despite knowing that the HindIII stock expired in 2002. Results are shown on '''Gel 6''' lanes 1 to 4. In all cases a 0.6kb band was excised, consistent with ''dxs'' insert. It therefore seems likely that M2, M3, M4 and M6 all represent pSB1A2+''dxs'' coding sequence BioBrick.
| |
| - | * Also did fusion PCR for the BABEL1+''glgC'' and BABEL2+''glgC'' constructs, using 1μl of L3 and L4 as templates ('''P4 and P5'''). Kod was used, with primers stdvectf1 and glgCr1, annealing at 65°C and extending for 110 seconds. Results are shown on '''Gel 6''' lanes 5 and 6. P4 (BABEL1) has a strong band the right size and would probably work if self-ligated, but P5 (BABEL2) shows strong bands at 2 and 3 kb, as CK is also seeing. I suspect that primer stdvectf1 does not work well with BABEL2 - possibly mis-anneals to the other end of the vector. In any event, we can delay the decision as to whether or not to carry on with these until we know the results from M10 and M11.
| |
| - |
| |
| - | ==== Wednesday 2 July 2008 ====
| |
| - |
| |
| - | * Digests of M10 and M11 with EcoRI, to determine orientation, were not very clear ('''Gel 7'''). Probably simpler just to sequence them, since we will need to check that the ends are intact in any case. Ordered mutagenic primers to remove the EcoRI sites:<br />
| |
| - | '''primer glgcm1f:''' tgttgaaaaacctgctaaccc<br />

| |
| - | ==== Thursday 3 July 2008 ====
| |
| - |
| |
| - | * Clones M2, M10 and M11 were submitted for sequencing using primers pSB1A2f1 and pSB1A2r1 (for M2) and pTG262f1 and pTG262r1 (for M10 and M11). We should get the results on Monday.
| |
| - | * Ordered primers to make carotenoid biosynthesis BioBricks:<br />
| |
| - | '''primer crtIf2:''' gat gaattc gcggccgc t tctag atg aaa cca act acg gta att g<br />
| |
| - | 22 matches, 8 GC = 32 C, 14 AT = 28 C, total 60°C, total length = 45<br />

| |
| - | 86.4°C, very strong, no<br />
| |
| - | Note that we already have a compliant ''crtE'' BioBrick (I hope), and the reverse primers crtBr2 and crtYr2 should be fine (see iGEM2007 lab book, page 90).
| |
| - | * Retransformed JM109 with the remainder of the ''appY'' ligation (I re-ligated it, and also heat-treated it before the transformation, since Tom Knight reports that this can increase transformation efficiency). Plated this to '''Plates 15 and 16'''.
| |
| - |
| |
| - | ==== Friday 4 July 2008 ====
| |
| - |
| |
| - | * Repeat ''appY'' transformation has failed: no colonies on plates 15 and 16. It seems unlikely that there is a major problem with the competent cells since other transformations have worked. Other than this, the only way to get no colonies (not even recircularized vector) is if something went seriously wrong in the original digest.
| |
| - | * Mutagenic primers for ''glgC'' arrived. Prepared 500μM stock solutions and 10μM working solutions. Tried PCR with both primer pairs using M11 (0.5μl) as template, just to check that the primers are OK. Annealing was at 57°C (lowest melting temperature of a primer) and extension for 110 seconds using Kod ('''PCR reactions P6 and P7'''). Products (5μl) were run on '''Gel 8'''. P6 (M1) shows a single rather faint band at 4.2kb; P7 (M2) shows multiple bands, with the 4.2kb band strongest. Probably both pairs are fine for MABEL. Now we just need to wait for the sequencing results on Monday.
| |
| - | * Also ran the other 5μl left from the religated L2 on gel 8. No DNA was visible. Did another digest (30μl total volume with 2μl each P2 and Edinbrick1, using Buffer E with EcoRI and SpeI, digesting at 37°C for about 5 hours, mainly because I forgot about it). Purified and ligated: Ligation '''L5'''.
| |
| - |
| |
| - | ==== Saturday 5 July 2008 ====
| |
| - |
| |
| - | * Streaked ''Pantoea ananatis'' DSM 30080 from cryogenic stock to LA ('''Plate 17''') and incubated at 30°C so that we will have a fresh stock of cells to make the ''crt'' BioBricks. Transformed competent cells tube J21 with ligation L5 (pSB1A2+''appY'')('''Plates 18 and 19''').
| |
| - |
| |
| - | ==== Sunday 6 July 2008 ====
| |
| - |
| |
| - | * Result of ''appY'' transformation: one white colony (subcultured to '''plate 20'''). Several more possible small white ones right at the edge: plate left overnight to grow a bit more.
| |
| - |
| |
| - | === Week 4 ===
| |
| - | ==== Monday 7 July 2008 ====
| |
| - |
| |
| - | * Several more white colonies have grown on plate 19, but quite small and close together. Tried to sub these to '''Plate 21'''.
| |
| - | * Nimisha and the team did two maxipreps - '''X1''' (J33201), and '''X2''' (the ''dxs'' clone of miniprep M2). X2 digested with HindIII (single restriction digest).
| |
| - | * Purified the mutagenic PCR reactions P6 and P7, and set up self ligations ('''L6 and L7''').
| |
| - | * Sequence results for ''glgC'' clones M10 and M11 show that both are in reverse orientation. The result for the ''dxs'' clones M2 looks OK at first glance, but can't see restriction sites since sequencing primers pSB1A2insf1 and pSB1A2insr1 were used rather than pSB1A2f2 and pSB1A2r2.
| |
| - |
| |
| - | ==== Tuesday 8 July 2008 ====
| |
| - |
| |
| - | * New primers for ''crt'' BioBricks arrived. Performed PCR with Kod using primer pairs crtBf2 (new) + crtBr2 (old)('''P8'''), crtIf2 + crtIr2 (both new) ('''P9'''), and crtYf2 (new) + crtYr2 (old)('''P10'''). The template for P8 and P10 was a suspension of ''Pantoea ananatis'' cells from plate 17; for P9, Douglas's maxiprep DNA from 19 Feb (with the PstI sites mutated out) was used. In all cases annealing was at 55 C and extension for 30 seconds. '''Gel 9''' showed that P8 and P9 had worked, with pure products of the expected size seen, but no product was seen for P10.
| |
| - | * ''glgC'' mutagenesis: Transformed competent cells with ligation products L6 and L7; plated cells on '''Plates 22 and 23''' (L6) and '''Plates 24 and 25''' (L7).
| |
| - | * ''dxs'': Ran gel (Gel 9) to check size of X1 (J33201) and X2 (pSB1A2+''dxs'') HindIII restriction digest. The digest looked fine.
| |
| - |
| |
| - | ==== Wednesday 9 July 2008 ====
| |
| - |
| |
| - | * Results of L6 and L7 transformations: no colonies for L6, but 9 colonies were obtained from L7. These were subcultured to '''plates 26 and 27'''. By the end of the day, these had grown sufficiently for 6 overnight cultures to be set up for minipreps tomorrow. In theory, some or all of these should be ''glgC'' with EcoRI site 2 mutated out.
| |
| - | * Minipreps '''M13 to M18''' of possible pSB1A2+''appY' transformants. Digests with EcoRI/PstI were run on '''Gel 10'''. All but M13 looked OK (insert band on M14 was so faint as to be ambiguous, but M15 to M18 all look good).
| |
| - | * Digests and ligation '''L8''' for addition of a synthetic ribosome binding site M2 (which has now been entered into the Registry as '''BBa_K118000''').
| |
| - |
| |
| - | ==== Thursday 10 July 2008 ====
| |
| - |
| |
| - | * Subitted M15 (possible pSB1A2+''appY'') for sequencing with primers pSB1A2insf2 and pSB1A2insr2.
| |
| - | * Minipreps '''M19 to M24''' of possible ''glgC'' mutants with EcoRI site 2 removed. EcoRI digests were run on '''Gel 11'''. The insert bands are a bit fuzzy, but it looks as though '''M19, M21 and M22''' may have lost the site, and M20, M23 and M24 may still have it.
| |
| - | * PCR '''P11''' using ligation L8 as template to generate a fusion product of rbs+''dxs''. Run on '''Gel 11''', last lane. No product visible.
| |
| - | * Digested P8 and P9 (''crtB'' and ''crtI''-mut PCR products) with EcoRI/SpeI together with Edinbrick1, purified and ligated (ligations '''L9 and L10''') at 16°C overnight.
| |
| - |
| |
| - | ==== Friday 11 July 2008 ====
| |
| - |
| |
| - | * Submitted M19, M21 and M22 for sequencing using primer pTG262f1, to check for clean removal of the EcoRI site.
| |
| - | * Revived ''Cellulomonas fimi'' in NB and plated to NA and NA+glucose. '''Plates 28 and 29''' incubated at 30°C.
| |
| - | * ZY and XH repeated rbs+''dxs'' ligation ('''L11''').
| |
| - | * Transformation of JM109 with L9 (pSB1A2+''crtB'' )and L10 (pSB1A2+''crtI''-mut). '''Plates 30 to 33'''.
| |
| - | * possible rbs+''dxs'' clones from un-numbered plates were streaked to '''plate 34'''.
| |
| - |
| |
| - | ==== Saturday 12 July 2008 ====
| |
| - |
| |
| - | * Result of transformation: ''crtB'' 100μl, 22 white and 10 blue; 900μl, too numerous to count, about two thirds white; a few blue showed signs of phage-like lysis. For ''crtI'' mutant, 100μl, 4 white and 2 blue; 900μl, 143 white and 25 blue. White ''crtB'' colonies were patched to '''Plate 35''', ''crtI'' to '''Plate 36'''.
| |
| - | * Set up overnight cultures of possible rbs+''dxs'' clones from plate 34 for minipreps.
| |
| - |
| |
| - | ==== Sunday 13 July 2008 ====
| |
| - |
| |
| - | * Signs of growth on ''Cellulomonas'' plates 28 and 29.
| |
| - | * '''Minipreps M25 to M30''' of possible rbs+''dxs'' clones from plate 34.
| |
| - | * '''PCR P12''' to obtain rbs+''dxs'' fusion product in case minipreps didn't work. Template was ligation L11, and primers were rbs2clonf1 and pSB1A2insr1. Annealing was 58°C, extension 40 seconds using Kod.

| - | * Digests and ligation '''L12''' to add rbs to ''appY'' clone M15 (sequence back today, seems OK).
| |
| - | * Minipreps '''M31 to M42''' of ''crtB'' and ''crtI'' clones. Digests with EcoRI/PstI. (AM)
| |
| - |
| |
| - | ==== Tuesday 15 July 08 ====
| |
| - |
| |
| - | * PCR '''P15''': fusion PCR of rbs+''appY'' using L15 as template. Extension 20 seconds, annealing 58°C, same primer set as before. '''Gel 13''' shows that it worked OK.
| |
| - | * '''Gel 13''' also shows digests of M31 to M42 from yesterday.
| |
| - | * Transformation of JM109 with ligations L13 and L15 (''glgC'' mutation and rbs+''dxs'' cloning). Plated to '''plates 39 to 41'''.

| |
| - | Meeting with other UK iGEM teams.
| |
| - |
| |
| - | ==== Thursday 17 July 08 ====
| |
| - |
| |
| - | * PCR for ''cenA'', ''cenB'', ''cenC'' and ''cex'' ('''P16''', '''P17''', '''P18''', '''P19'''). Annealing 58°C, extension 115 seconds (''cenB'' and ''cenC'' are both over 3kb) and included 5% v/v glycerol in the reactions since in the past that has been helpful with high GC templates. PCR products purified to be run on gel tomorrow (against wisdom, since they should have been run on gel both before and after purification).
| |
| - | * Results of transformations: plenty of colonies for ''glgC'' mutation (mutating site 1 in the mutant which already has site 2 mutated). Subbed some of these to '''plates 42, 44 and 45''' (poor communications). Only a few colonies for rbs+''dxs'', and only one of these was white. Subbed this to '''plate 43'''. Apparently there may have been some problem with the purification of this digest - may need to repeat.
| |
| - | * Re-digested M32, M36 (''pSB1A2-crtB''), M39 and M40 (''pSB1A2-crtI'') and ran on '''Gel 15'''. Gel unsuccessful - stain smeared over 0.5-2kb region, exactly where ''crtB'' and ''crtI'' bands are expected to appear. Perhaps too much loading buffer or problem with the tank (tank with 'loose wire' was used). (AM)
| |
| - | * pSB1A2+''appY'' cultures set up in beaker for maxiprep tomorrow ('''X3'''). (AM)
| |
| - |
| |
| - | ==== Friday 18 July 08 ====
| |
| - |
| |
| - | * Made pSB1A2+''appY'' Maxiprep *X3*. (AM)
| |
| - | * Purified PCR products for ''cenA'', ''cenB'', ''cenC'' and ''cex'' ('''P16''', '''P17''', '''P18''', '''P19''') run on '''Gel 16'''. No visible bands. (AM)
| |
| - | * Second attempt at PCR for ''cenA'', ''cenB'', ''cenC'' and ''cex'' ('''P20''', '''P21''', '''P22''', '''P23'''). Annealing 55°C, extension 85 seconds; did ''not'' include glycerol. Ran unpurified PCR products on '''Gel 17''' - no bands apart from thick bands in the <0.5kb region = primers. Hence, PCR was unsuccessful. (AM)
| |
| - |
| |
| - | ==== Saturday 19 July 08 ====
| |
| - |
| |
| - | * Minipreps '''M43 to M47''' of possible ''glgC'' double mutants (both EcoRI sites gone), and '''M48''' of the only white colony from the pSB1A2+rbs+''dxs'' transformation. '''Gel 18''' shows EcoRI/PstI digests of 3μl. M43 to M47 all look about right: send one for sequencing. M48 is ambiguous, could be incomplete deigestion, need to repeat. (CF)
| |
| - | * PCR '''P24 and P25''', repeat PCR for ''cenA'' and ''cex'' (the two shorter genes) using Pfu polymerase instead of Kod, adding 5% glycerol - this worked well for high-GC genes from ''Saccharothrix espanaensis'' last year. (CF)
| |
| - |
| |
| - | ==== Sunday 20 July 08 ====
| |
| - |
| |
| - | * Ran P24 and P25 on '''Gel 19'''. No amplification products. Time to do some trouble shooting. The fault is in either the primers, the template, or the reactions. All previous reactions have been fine, so most likely the primers or template. To check this, we need to do a positive control using universal primers such as fd1 and rd1 (amplify 16S rRNA gene ''rrnB'') which should definitely give a product. If these fail, then it is most likely that the template is at fault - we should prepare genomic DNA and try using this as template rather than cells; also do a Gram stain to confirm that the cells look OK. If the control reaction works, try remaking the primer solutions, though it seems unlikely that all four sets could be wrong, unless I was having a really bad day. (CF)
| |
| - | * Redid digest of M48 with SacI/Spe1. Does not look good. Also repeated digests of ''crtB'' and ''crtI'' clones M36 and M42; alternating single digests (EcoRI) and double digests (EcoRI/PstI) to check for inserts. Look OK. Submit for sequencing. (CF)
| |
| - | * Also: I have a plan for in vitro assembly to cut down on transformations and minipreps. Could have a try of this next week if there are some students with some free time. (CF)

| |
| - | * Overnight culture of ''C. fimi'' did not yield sufficient cells. Made two more cultures in nutrient broth; all cultures incubated at 30°C with shaking. (AM)
| |
| - | * PCR of ''crtY'' from ''P. ananatis'' cells ('''P27''') and ''crtB'' and ''crtI'' from ligations L17 and L18 respectively ('''P28, P29'''). PCR products were run on '''Gel 22''' ~ P28 and P29 successful, P27 unsuccessful. (AM, YZJ, OG)
| |
| - | * Re-did positive control PCR for ''rrnB'' from ''C. fimi'' ('''P30''') ~ denaturing at 95°C for 20s, annealing at 55°C for 1 minute, extension at 70°C for 30s. The first two settings were in error; ''denaturing'' should have been set to 1 minute and annealing to 10 sec as usual. HOWEVER, annealing for 1 minute appears to have worked, so it might be worth trying this for PCRing the cellulases. (AM)
| |
| - | * P30 (the above) and pZntA were run on '''Gel 23'''. Both successful. (AM)

| |
| - |
| |
| - | * Purified PCR products P28 and P29 (OG)
| |
| - | * Double digestions using XbaI/PstI (buffer H) to add P12 (rbs+''dxs''), P15 (rbs+''appY''), P28 (rbs+''crtB'') and P29 (rbs+''crtI'') to Edinbrick1. (Yan, OG)
| |
| - | * Double digestion using SacI/SpeI (BufferE) to add P31 (pZntA) to Edinbrick1. (Yan, OG)
| |
| - | * Purified genomic DNA from ''C. fimi'' culture (made from plate 37, incubated in 25ml bottle at 30C for 48 hours with shaking). Used Promega Wizard Genomic DNA Purification Kit, lysozyme and RNAse+EDTA (as replacement for proprietary RNAse Solution, of which none was left). Final solution left overnight in refrigerator at 4°C. (AM)
| |
| - | * Plated ''C. fimi'' culture from plate 37...
| |
| - | ** Incubated in 25ml bottle for 48 hours at 30°C with shaking ... to '''Plate 48'''.
| |
| - | ** Incubated in 50ml bottle for 24 hours at 30°C with shaking ... to '''Plate 49'''.
| |
| - | ** Incubated in 250ml flask for 24 hours at 30°C with shaking ... to '''Plate 50'''. (AM)
| |
| - | * PCR of ''cenA'' ('''P32'''), ''cenB'' ('''P33'''), ''cenC'' ('''P34'''), ''cex'' ('''P35'''), annealing 1 min 55°C, extension 90 sec 70°C. Run on '''Gel 24''' ~ unsuccessful. (AM)

| |
| - | ==== Friday 25 July 08 ====
| |
| - |
| |
| - | * Made maxiprep '''X4''' (pSB1A2-''crtB'' as M36; BBa_K118002) and '''X5''' (pSB1A2-''crtI'' as M42; BBa_K118003) (AH, XH)
| |
| - | * Ligation of P29 into Edinbrick1 to make '''L22''' (pSB1A2+rbs+''crtI''). (Yan, OG)
| |
| - | * Ligation of P28 into Edinbrick1 to make '''L21''' (pSB1A2+rbs+''crtB''). (Yan, OG)
| |
| - | * Ligation of P12 into Edinbrick1 to make '''L19''' (pSB1A2+rbs+''dxs''). (Yan, OG)
| |
| - | * Ligation of P15 into Edinbrick1 to make '''L20''' (pSB1A2+rbs+''appY''). (Yan, OG)
| |
| - | * Ligation of P31 into Edinbrick1 to make '''L23''' (pSB1A2+pZntA). (Yan, OG)
| |
| - | * ''C. fimi'' Plate 48 appears to be contaminated (mix of opaque and clear colonies). The same culture was used for genomic DNA purification yesterday ~ this preparation is therefore inadequate for sequencing purpose but might be worth using for PCR. (AM)
| |
| - | * No growth of ''C. fimi'' on Plates 49 and 50, but ''C. fimi'' takes a relatively long time to form colonies so we should check again on Monday. (AM)
| |
| - | * PCR '''P36''' of M43 (''glgC''-mut1,2) to excise the gene from BABEL and rectify its orientation and '''P37''' of ''crtY'' from ''P. ananatis'' (Plate 17) cell suspension - repeat of P27.
| |
| - | ** P36 and P37 run on '''Gel 25'''. P36 tentatively successful (larger than desirable smear in the region of interest), P37 failed.
| |
| - | * Also did preparations to transfer ''crtE'' from BABEL2 vector to pSB1A2. This is necessary, because we are supposed to use Registry standard vectors for all BioBricks we make (in fact, we should even stop using pSB1A2and move to pSB1A3). So, digested the BABEL2+''crtE'' clone that Douglas Leslie made with EcoRI and PstI, and also Edinbrick1 - in both cases, 3μl in 20μl total volume. Ran both on a gel and excised the appropriate bands, eluted each to 10μl EB and set up a ligation using 4μl of each in 10μl total volume. Ligated at 16°C. (CF)
| |
| - |
| |
| - | ==== Saturday 26 July 08 ====
| |
| - |
| |
| - | * Transformed JM109 with 5μl of ligations labelled as L12, L15, L28, L29, L31 (note: these ligations seem to have been numbered based on the PCR product they were derived from rather than sequentially; they have been renumbered as '''L19 to L23'''), plus my own ligation ('''L24''') which was to transfer ''crtE'' from the BABEL vector (which is not an 'official' BioBrick vector, though it is fully compliant) to pSB1A2, so that we can submit it to the Registry. These were plated on '''plates 51 to 62.''' (CF)
| |
| - |
| |
| - | ==== Sunday 27 July 08 ====
| |
| - |
| |
| - | * Result of transformations: no growth for 'L12' (L19), 'L15' (L20) or 'L28' (L21). For 'L29' (L22) there are some blue and white colonies. For 'L31' (L23) there are many blue colonies but only a few white ones, suggesting that the SacI/SpeI double digest is less efficient than the XbaI/PstI which was (I hope) used for the others. For the ''crtE'' ligation, there are many white colonies and very few blue - this is as expected, since in this case the vector and insert bands were purified from a gel. (CF)
| |
| - |
| |
| - | === Week 7 ===
| |
| - | ==== Monday 28 July 08 ====
| |
| - |
| |
| - | * Repeated transformation of L20 and L21, and plated on plate 63 to 66. (YAN and Omar).
| |
| - | * PCR of _cenA_, _cenB_, _cenC_ and _cex_ from cell suspension (*P38~41*; cell solution incubated at 80~73C for 8 minutes to kill cells/inactivate DNAse) and DNA solution 'purified' from contaminated cell culture (*P42~45*). Denaturing 95C for 1 min, annealing 55C for 10s, extension 70C for 90s. PCR products run on *Gel 26*. (AM)
| |
| - | * Prepared *L25* of P36 (_glgC_ double mutant PCRed with primers f2 and r2) and Edinbrick 1. (AM)
| |
| - | * Minipreps *M49 to M54* of pSB1A2-rbs+crtI transformants. (CF)
| |
| - |
| |
| - | ==== Tuesday 29 July 08 ====
| |
| - |
| |
| - | * Transformation of L20 and L21 failed.
| |
| - | * Transformation of glgc mutant 1&2 ligation product, made *plate 67 & 68* (Yan)
| |
| - | * Cut out putative _cenA_ and _cex_ (both \~1.5kb) fragments from gel 27 (repeat of Gel 26 but stained with SYBRsafe). Purified DNA from gel fragments: *F1* (putative _cenA_) and *F2* (putative _cex_). (AM)
| |
| - | * Digests of M49 to M54 (pSB1A2-rbs+crtI) with EcoRI alone. This should generate a single 4 kb band (doing a double digest with EcoRI and PstI would give a vector and insert band both around 2 kb, which would probably run at the same place, making it hard to tell whether there was an insert). These were run on *Gel 28*. All showed a single band at the expected place. (CF)
| |
| - | * Minipreps of PZntA (*M55 to M60*) from L23 (Yan & Nimisha)
| |
| - | * Minipreps of CrtE+RBS (*M61 to M66*) from L22 (Yan & Nimisha)
| |
| - | ** Double digests of M55 to M60 and M61 to M66 with EcoRI and PstI. This should generate the following bands: \~2.2 kb for PZntA (M55 to M60), \~1.1 kb for crtE+RBS (M61 to M66), and \~2 kb for the vector. These were run on *Gel 29*. M55 to M60 unsuccessful; M61 to M66 showed a band at the expected location for crtE+RBS but seemed to be indicate that L22 was still ligated into BABEL instead of pSB1A2. (Yan & AM)
| |
| - |
| |
| - | ==== Wednesday 30 July 08 ====
| |
| - |
| |
| - | * *P48* (_crtY_) and *P49* (Recreation of P12, rbs\+_dxs_) created (30.07.08: CF)
| |
| - | * Ligated F1 (putative _cenA_) and F2 (putative _cex_) to Edinbrick 1 (*L28* and *L29* respectively). All were digested with EcoRI and SpeI, purified and stored overnight in the 16C water bath. (AM)
| |
| - | * Repeated PCR for _cenA_ and _cex_ (*P46, P47*) from heat killed cell solution. Denaturing 95C for 1 min, annealing 65C for 10s, extension 70C for 40s. Run on *Gel 30*. Unsuccessful, perhaps because annealing temperature was too high (temperature was decided based on stock solution label, which took the prefix/suffix into consideration). (AM)
| |
| - | * Gel 31*: M49 (X,SX,sac/spt), M50(X,SX,sac/spt), M63(E,EP), M67(E/P, sac1/spe1), P48(crtY). (OG)
| |
| - | * *Re-digested* M55 to M60 with (a) EcoRI and (b) EcoRI and PstI. (This time, the amount of DNA for digestion is increased). (Yan)
| |
| - | ** *Gel 32* results look promising for M57, but not for the others. (Yan)
| |
| - | * Purified Edi+P15 XP and Edi+P28 XP and set-up for ligations (*L26* and *L27*), stored overnight in the 16C water bath.(HX)
| |

| |
| - | ==== Thursday 31 July 08 ====
| |
| - |
| |
| - | * M50 (rbs\-_crtI_), M63 (rbs\-_crtE_) and M67 (rbs\-_crtB_(?) ) submitted for sequencing. (CF)
| |
| - | * Transformation of L26(Edi+P15\[rbs+appY\]XP) to Plate 75,76; L27(Edi+P28\[crtB+rbs\]XP) to Plate 77,78; L28(Edi\+ cenA) to Plates 79,80 and L29(Edi+cex) to Plate 81,82. (HX)
| |
| - | * Minipreps of *M68 to M79:* M68 to M71 are glgc mutant 1 &2 (1-4) in Edinbrick1, *M72* and *M75* are RBS+dxs in Edinbrick 1, and *M76* to *M79* are CrtE in Babel2 (YAN & AM)

| |
| - | ==== Friday 1 August 08 ====
| |
| - |
| |
| - | * Primers for PcstA ordered. (CF)
| |
| - | * White colonies from Thursday's transformations were subplated as follows...
| |
| - | ** Plate 76 (L26: Ed1-rbs+appY) \--> *Plate 83*.
| |
| - | ** Plate 77 (L27: Ed1-rbs+crtB) \--> *Plate 84*.
| |
| - | ** Plate 80 (L28: Ed1+cenA) \--> *Plate 85*.
| |
| - | ** Plates 81/82 (L29: Ed1+cex) \--> *Plate 86*. (AM/HX/OG)
| |
| - | * Digested minipreps M68 to M71 (pSB1A2-glgC mutant 1+2), M72 to M75 (pSB1A2-rbs+dxs), M76 to M79 (Babel2-crtE) as follows...
| |
| - | ** _First digestion_: M68~71 with EcoRI+PstI, M72~75 with EcoRI, M79~79 with EcoRI+PstI. Run on *Gel 33*. Results: M79, 69, 71 - vector band around 2 kb, no glgC band; M72, 73, 74 - single band around 4 kb, expected length for vector+gene; M79~79 - crtE band < 1 kb, vector band around 2 kb. It is not clear into which vector crtE (M76~79) is inserted, so sequencing will be necessary.
| |
| - | ** _Second digestion_: M68 and M69 with (1) EcoRI alone and (2) EcoRI+PstI; M72 with (1) EcoRI alone and (2) SacI+SpeI. Run on *Gel 34*. Results: Single and double digests of M68 and M69 yielded similar results, hence pSB1A2-glgC ligation or transformation failed; digests of M72 yielded expected bands, hence pSB1A2-dxs+rbs successful. (AM)
| |
| - | * P36 (glgC mutants 1+2, excision from Babel vector) and L25 (ligation of P36 to Edinbrick 1) were run again on *Gel 35*. Results: P36, viewed at lower illumination, yields one band of the desired length (1.5kb, length of glgC); L25 yields two bands around 1.5kb, a thick band at 3kb and several fainter bands including one at 2kb (length of pSB1A2). (AM)

| |
| - | === Week 8 ===
| |
| - | ==== Monday 4 August ====
| |
| - |
| |
| - | * Made 17 minipreps from transformations of L26, L27, L28, L29. Those are: *M80* to *M83* (RBS+AppY in Edinbrick) from L26, *M84* to *M85* (RBS+CrtB in Edinbrick) from L27, *M86* to *M90* (CenA in Edinbrick) from L28 and *M91* to *M96* (Cex in Edinbrick) from L29. This was followed by double digestion of all the miniprep products (M80 to M96) with EcoRI and PstI. (YAN&OG)
| |
| - | * Third glgC mutagenesis on Babel-glgC (since Edinbrick-glgC appears to have failed), *P50* made. (YAN)
| |
| - | * Sequencing results back today indicate that M50 = rbs\-_crtI_, M63 = BABEL2-rbs\-_crtE_ and M67 = rbs\-_crtB_.
| |
| - | * Double digestion of M80 to M96 with EcoRI and PstI, and PCR production of third mutagenesis of glgc mutant 1&2 were run on the *gel 36.* Results were good for M80-82 (rbs\-_appY_\-pSB1A2), M84-85 (rbs\-_crtB_\-pSB1A2), M92 (_cex_\-pSB1A2) and P50 (_glgC_\-mut1,2+3). Other results were poor, with bands in the wrong position for M86-M90 (_cenA_\-pSB1A2). (YAN&OG).

| |
| - | ==== Tuesday 5 August ====
| |
| - |
| |
| - | * M72 (rbs\-_dxs_\-pSB1A2), M79 (BABEL2\-_crtE_) and M82 (rbs\-_appY_\-pSB1A2) submitted for seqencing. (CF)
| |
| - | * Minipreps of CenA (2, 7-13), made *M97* to *M104* (CenA in Edi); Minipreps of Cex (7-10), made *M105* to *M108* (Cex in Edi) (YAN).
| |
| - | * M97 to M108 were double-digested with EcoRI and PstI,and run on *gel 37*.(YAN)
| |
| - | * Purify P50 (3rd mutagenesis of _glgc_ mutant1&2) and self-ligate it (L30). (HX)
| |
| - | * M68-69 (_glgC_\-mut1+2 in pSB1A2) and M92 (_cex_\-pSB1A2) were digested with a) PstI and b) EcoRI and PstI, but gel leaked. Entire process neeeds repeating tomorrow\! (CF & OG)
| |
| - | * Digested p36 with Edinbrick1 using Spe1 and EcoR1, to be continued tomorrow (OG)
| |
| - | * *Plate 93* created from subculture of plate 56 (M67, pSB1A2-rbs\-_crtB_)

| - |
| |
| - | * *L31* ligation of P36 (_glgC_\-mut1+2, hopefully, could be P39) to Edinbrick1 completed (OG)
| |
| - | * Primers have arrived for PcstA. Chris carried out the PCR (that would be *P51*). Unsuccessful. (CF)
| |
| - | * Digestion of M67 (rbs-crtB) with EcoRI/SpeI, M50 (rbs-crtI) with EcoRI/XbaI, in preparation for combining the two with the former as insert and the latter as vector. (CF)
| |
| - | ** Not enough time to purify/ligate due to high demand for agarose gel following lunchtime. Shall do tomorrow morning at 9. (AM)
| |
| - | * Re-digestion of M97, M98, M99, M101 (all pSB1A2\-_cenA_) and M105, M108 (pSB1A2\-_cex_) with 1)EcoRI and 2) EcorI/PstI; and M92 with 1)PstI and 2)EcoRI and PstI, run on gel 38 (because gel 37 did not look good). (YAN)
| |
| - | * Transformation of L30 on blue white plate (plate 89,90) and L31 on blue white plate (plate 91,92). (HX)
| |
| - | * Maxipreps X6 (from M50: rbs+crtI) and X7 (from M63: BABEL2-rbs+crtE). (AM)
| |
| - | * Overnight culture made from plate 93 (M67, pSB1A2-rbs\-_crtB_) ready for maxiprep tomorrow. (AM, AH)
| |
| - | * Analytical digests using a) EcoRI and b) EcoRI/PstI of M70, M71 (both pSB1A2\-_glgC_ mut1+2) and M92 (pSB1A2\-_cex_). Run on *gel 38*. Results do not look good. Bands are wrong size to correspond to vector and no bands match an expected insert size. (CF)

| - |
| |
| - | ==== Thursday 7 August 08 ====
| |
| - |
| |
| - | * Subculture from Plate 89,90 (transformation of L30) to Plate 94; Plate 91 (L31) showed no growth, s was discarded. Plate 92 (L31) had a blue smear and two white colonies. These colonies were subbed to Plate 95. (HX)
| |
| - | * Maxiprep *X8* (pSB1A2-rbs\-_crtB_, as M67) made. Slight hiccup after step 6. (Cold solution 3 was added and incubation on ice was skipped. Centrifugation continued for 2 minutes before mistake was realised, after which the solution was mixed and incubated on ice for ten minutes (continuing with step 7). (AM & AH)
| |
| - | * Combination (Ligation) of Biobricks of CrtB (from M67) and CrtI (from M50):CrtB as an insert cut with EcoRI/SpeI; CrtI as a vector cut with EcoRI/XbaI (*L32*). (YAN, AM)
| |
| - | * Double digestion of three biobricks: 2 of dxs (from M72), CrtE (from M63) and Lims (from 0713536 in igem 07 box): dxs as a vector cut with SpeI/PstI; CrtE as an insert cut with XbaI/PstI; Lims as a vector cut with XbaI/PstI.
