| | | | |
| - | = Lab Notebook =
| + | Up-to-date to end 28 October. |
| - | === Week 5 ===
| + | |
| - | ==== Monday 14 July 08 ====
| + | |
| - | | + | |
| - | * 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 20s, 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'''.
| + | |
| - | | + | |
| - | ==== Wednesday 16 July 08 ====
| + | |
| - | | + | |
| - | 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 115s (''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 85s; 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)

| - | ==== Monday 21 July 08 ====
| + | |
| - | | + | |
| - | * M36 (''crtB''), M42 (''crtI'') and M43 (''glgC''-mut1,2) submitted for sequencing. (AH)
| + | |
| - | * Plates 46 and 46 have no colonies (white or blue) - Something went wrong with the transformation. (AH)
| + | |
| - | | + | |
| - | ==== Tuesday 22 July 08 ====
| + | |
| - | | + | |
| - | * Positive control PCR with universal primers fd1 and rd1 to amplify 16S rRNA gene ''rrnB'' from ''C. fimi'' ('''P26'''); PCR products run on '''Gel 21''' - failed. (AM)
| + | |
| - | * Made overnight culture of ''C. fimi'' from plate 37 for chromosomal DNA purification tomorrow. (AM)
| + | |
| - | * M36 (''crtB'') and M42 (''crtI'') double digested, ligated with rbs to make '''L17''' (M36) and '''L18''' (M42). (YAN & OG)
| + | |
| - | * L15 (rbs+''dxs'' ligation to Edinbrick1) and L16 (rbs+''appY'' ligation to Edinbrick1) run on gel, the result showed the ligations into edinbrick1 failed. (YAN & OG)
| + | |
| - | | + | |
| - | ==== Wednesday 23 July 08 ====
| + | |
| - | | + | |
| - | * M43 (''glgC''-mut1,2) sequence results received. First and second mutation sites successfully removed. (AH)
| + | |
| - | * 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)
| + | |
| - | | + | |
| - | ==== Thursday 24 July 08 ====
| + | |
| - | | + | |
| - | * 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 (pSB1A2+rbs+''appY'') and L21 (pSB1A2+rbs+''crtB''), and plated on ''plates 63 to 66''. (YAN and Omar).
| + | |
| - | * PCR of ''cenA'', ''cenB'', ''cenC'' and ''cex'' from cell suspension ('''P38-41'''; cell solution incubated at 73-80°C for 8 minutes to kill cells/inactivate DNAse) and DNA solution 'purified' from contaminated cell culture ('''P42-45'''). Denaturing 95°C for 1 min, annealing 55°C for 10s, extension 70°C for 90s. PCR products run on '''Gel 26'''. (AM)
| + | |
| - | * Prepared '''L25''' of P36 (''glgC''-mut1,2 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''-mut1,2 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 an EcoRI/PstI double digest 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 pSB1A2+pZntA ('''M55 to M60''') from L23 (Yan, Nimisha)
| + | |
| - | * Minipreps of pSB1A2+rbs+''crtE'' ('''M61 to M66''') from L22 (Yan, Nimisha)
| + | |
| - | ** Double digests of M55 to M60 and M61 to M66 with EcoRI/PstI. This should generate the following bands: ~2.2 kb for pZntA (M55 to M60), ~1.1 kb for rbs+''crtE'' (M61 to M66), and ~2 kb for the pSB1A2 vector. These were run on '''Gel 29'''. M55 to M60 unsuccessful; M61 to M66 showed a band at the expected location for rbs+''crtE'' but seemed to be indicate that L22 was still ligated into BABEL2 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/SpeI, purified and stored overnight in the 16°C water bath. (AM)
| + | |
| - | * Repeated PCR for ''cenA'' and ''cex'' ('''P46''', '''P47''') from heat killed cell solution. Denaturing 95°C for 1 min, annealing 65°C for 10s, extension 70°C 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 and M50 (pSB1A2-rbs+''crtI'' digested with a) XbaI, b) SpeI/XbaI, c) sac/speI), M63 (BABEL2+rbs+''crtE'' digested with a) EcoRI, b) EcoRI/PstI), M67 (pSB1A2+rbs+''crtB'' digested with a) EcoRI/PstI, b) sacI/speI) and P48 (''crtY''). (OG)
| + | |
| - | * Re-digested M55 to M60 (pSB1A2+pZntA) with a) EcoRI and b) EcoRI/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 P15 (rbs+''appY'') and P28 (''crtB''), digested each with EdinbrickI using XbaI/PstI and set-up for ligations ('''L26''' and '''L27'''). Stored overnight in the 16°C water bath.(HX)

| - | | + | |
| - | * Primers for pCstA ordered. (CF)
| + | |
| - | * White colonies from Thursday's transformations were subplated as follows...
| + | |
| - | ** Plate 76 (L26: pSB1A2+rbs+''appY'') to '''Plate 83'''
| + | |
| - | ** Plate 77 (L27: pSB1A2+rbs+''crtB'') to '''Plate 84'''
| + | |
| - | ** Plate 80 (L28: pSB1A2+''cenA'') to '''Plate 85'''
| + | |
| - | ** Plates 81/82 (L29: pSB1A2+''cex'') to '''Plate 86'''. (AM/HX/OG)
| + | |
| - | * ''First digestion'': M68 to M71 (pSB1A2+''glgC''-mut1,2) with EcoRI/PstI, M72 to M75 (pSB1A2+rbs+''dxs'') with EcoRI, M76 to M79 (BABEL2+''crtE'') with EcoRI/PstI. Run on '''Gel 33'''. Results: M68, 69, 71: vector band around 2 kb, no ''glgC'' band; M72, 73, 74: single band around 4 kb, expected length for vector+gene; M76-79: ''crtE'' band <1 kb, vector band ~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 a) EcoRI, b) EcoRI/PstI; M72 with a) EcoRI b) SacI/SpeI. Run on '''Gel 34'''. Results: Single and double digests of M68 and M69 yielded similar results, hence pSB1A2+''glgC''-mut1,2 ligation or transformation failed; digests of M72 yielded expected bands, hence pSB1A2+rbs+''dxs'' successful. (AM)
| + | |
| - | * P36 (''glgC''-mut1,2 excision from BABEL2) and L25 (P36 + Edinbrick1) were run again on '''Gel 35'''. Results: P36 viewed at lower illumination yields one band of the desired length (1.5kb); L25 yields two bands around 1.5kb, a thick band at 3kb and several fainter bands including one at 2kb (length of pSB1A2).

| - | * Made 17 minipreps from transformations of L26, L27, L28, L29: '''M80-83''' (L26: rbs+''appY'' in Edinbrick1), '''M84-85''' (L27: rbs+''crtB'' in Edinbrick1), '''M86-90''' (L28: ''cenA'' in Edinbrick1) and '''M91-96''' (L29: ''cex'' in Edinbrick1). This was followed by double digestion of all the miniprep products (M80-96) with EcoRI/PstI. (Yan, OG)
| + | |
| - | * Third ''glgC'' mutagenesis made by MABEL on BABEL2+''glgC''-mut1,2 (since pSB1A2+''glgC''-mut1,2 appears to have failed) performed: '''P50''' (Yan)
| + | |
| - | * Double digestions of M80 to M96 and P50 were run on '''gel 36'''. Results were good for M80-82 (pSB1A2+rbs+''appY''), M84-85 (pSB1A2+rbs+''crtB''), M92 (pSB1A2+''cex'') and P50 (''glgC''-mut1,2,3). Other results were poor, with bands in the wrong position for M86-M90 (pSB1A2+''cenA''). (Yan, OG)
| + | |
| - | * Sequencing results back today indicate that M50 = pSB1A2+rbs+''crtI'', M63 = pSB1A2+rbs+''crtE'' and M67 = pSB1A2+rbs+''crtB''. (AH)

| - | * Primers have arrived for pCstA. Chris carried out the PCR (that would be '''P51'''). Unsuccessful. (CF)
| + | |
| - | * Digestion of M67 (pSB1A2+rbs+''crtB'') with EcoRI/SpeI and M50 (pSB1A2+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)

| - | | + | |
| - | * Subcultured from Plates 89 and 90 (BABEL2+''glgC''-mut1,2,3) to '''Plate 94'''. Plate 91 (pSB1A2+''glgC''-mut1,2) showed no growth, so was discarded. Plate 92 (pSB1A2+''glgC''-mut1,2) had a blue smear and two white colonies. These colonies were subbed to '''Plate 95'''. (HX)
| + | |
| - | * Maxiprep '''X8''' (as M67: pSB1A2+rbs+''crtB'') 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)

| + | |
| - | * ''Arabidopsis'' ''isa1'' and ''isa2'' cDNAs have arrived as well as ''Zea mays'' ''su1'', ''iso2'' and ''iso3''. The ''Arabidopsis'' genes are full of forbidden restriction sites, so it would be best to use the maize genes. Primers will need to be designed. (AH)
| + | |
| - | * PCRed ''cenA'' and ''cex'' with a) KOD polymerase, b) Velocity polymerase separately to make '''P55''' (''cenA'' by KOD), '''P56''' (''cenA'' by Velocity), '''P57''' (''cex'' by KOD) and '''P58''' (''cex'' by Velocity). (Yan)

| - | ==== Monday 11 August 08 ====
| + | |
| - | | + | |
| - | * PCR products of P55 to P58 (''cenA'' and ''cex'') were run on '''Gel 41:''' ''cex'' with KOD polymerase (P57) generated a single band of the desired size. However, ''cex'' with Velocity polymerase and ''cenA'' with both KOD or Velocity polymerase failed. (YAN)
| + | |
| - | * PCR products P61 to P63 (''rrnB'', ''cenA'', ''cex'') were run on '''Gel 42'''. Very clear band for ''rrnB'', no bands for either ''cenA'' or ''cex''. (CF)
| + | |
| - | * Made '''Plate 109/110''' (Transformation of L33: pBS1A2+pCstA), '''111/112''' (transformation of L34: pBS1A2+''dxs''+''crtE'') and Plate '''113/114''' (Transformation of L35: pBS1A2+''dxs''+''lims1''). (Yan)
| + | |
| - | * Maxipreps '''X9''' of pSB1A2+rbs+''dxs'' (as for M72) and '''X10''' of pSB1A2P+rbs+''appY'' (as for M82). (AM)
| + | |
| - | * Redid PCR (KOD) of ''cex'' from ''C. fimi'' genomic DNA but with 10µl 50% glycerol, denaturing 1 min, annealing 60°C for 30s and extension 30s ('''P64'''). To be run on gel tomorrow. (AM)
| + | |
| - | * Digested P57 (''cex'' from KOD PCR) with EcoRI/PstI to confirm identity of the gene. ''cex'' has a PstI restriction site near its midpoint, so this digestion should generate two segments of approximately 750bp. To be run on gel tomorrow. (AM)
| + | |
| - | * Digests performed using EcoRI/PstI to move ''crtE'' from BABEL2 (M79) to Edinbrick1. In each case, 3µl of vector was digested in 20µl total volume. The digests were run on a gel ready for excision, but gel showed no band corresponding to ''crtE'' (see '''gel 43''' showing a single band at ~3kb for BABEL2+''crtE'' and bands at ~2.5kb and 800bp for Edinbrick1). (AH)
| + | |
| - | * '''M109-M112''' Minipreps of pSB1A2+''crtB''+''crtI'', from plates 102. '''M113-M116''' Minipreps of pSB1A2+''glgC''-mut1,2 from plate 103. '''M117-M120''' Minipreps of pSB1A2+''glgC''-mut1,2,3 from plate 94 (OG)
| + | |
| - | * Double digestion of M109 to M120 with EcoRI/PstI, run on '''gel 44'''. M110-102 (pSB1A2+''crtB''+''crtI'') have a band at 2.5kb as expected. M109 (pSB1A2+''crtB''+''crtI'') gave a band at 3kb instead, so should be ignored from now on. (Yan)

| + | |
| - | * Over-night cultures of L33 (pSB1A2+pCstA, sub-cloned on Plate 115), L34 (pSB1A2+''dxs''+''crtE'', sub-cloned on Plate 115) and L35 (pSB1A2+''dxs''+''lims1'', subcloned on Plate 115) set up, ready for minipreps tomorrow.
| + | |
| - | * '''M121-M123''': Minipreps of pSB1A2+''crtY'' (1,2,3). '''M124-M126''': Minipreps of pSB1A2+rbs+''crtY'' (1,2,3). note: I messed up M121 by adding 200µl instead of 100µl of sol 1. They are in the green box, the orange one is full. (OG)
| + | |
| - | * Double digests of M121 to M126, run on '''Gel 46'''. It looks good! M121 is good! (Yan)
| + | |
| - | * Purified P61 (''rrnB'') for sequencing. (CF/AM)
| + | |
| - | * Re-purified already purified genomic DNA from ''C. fimi''. This meaningless endeavour resulted from a misunderstanding. Hopefully, the doubly-purified DNA will still be useable. (AM)
| + | |
| - | * P57 (''cex'' from cells) EcoRI/PstI double digest, undigested P64 (''cex'' from genomic DNA), P66 (''su1'') and P67 (''iso2'') run on '''Gel 45'''. P57 double digest yielded no clear bands; P64 yielded a clear band at 1.5 kb. (CF/AM)
| + | |
| - | * Purified P57 (''cex'' from cell suspension) and P64 (''cex'' from genomic DNA). Digested both with PstI. (AM)
| + | |
| - | * PCR for ''cenA'' from ''C. fimi'' genomic DNA ('''P65'''): denaturing 1 min, annealing 56°C for 20s, extension 30s, with glycerol. (AM)
| + | |
| - | * P57 and P64 (''cex'') PstI digests and P65 (''cenA'') run on '''Gel 47'''. Results indicate success!. (AM)
| + | |
| - | * Re-did the excise of ''crtE'' from BABEL2 (M79); cut out the band responsible for ''crtE'' and Edinbrick 1 on the gel, followed by putification of ''crtE'' and Edinbrick1 from the cut-out gel. Finally, ligation of ''crtE'' to Edinbrick1 ('''L38'''). (HX, AH)
| + | |
| - | * Analytical digests as follows (AH):
| + | |
| - | ** M109 and M110 (pSB1A2+''crtB''+''crtI''): BamHI/EcoRV
| + | |
| - | ** M115 and M116 (pSB1A2+''glgC''-mut1,2): HindIII
| + | |
| - | ** M115 and M116 (pSB1A2+''glgC''-mut1,2): EcoRI/HindIII
| + | |
| - | * Digests of M109, M110, M115 and M116 were run on '''gel 48'''. M109 and M110 should give two bands if both genes are present. HindIII digest of M115/116 should give a single band indicating linearised plasmid with ''glgC''. Double digest of M115/116 should give an insert band of ~1kb and a vector + ~500bp of insert band. Results do not look good. Bands seem to indicate much too large products, but will discuss with Chris tomorrow.(AH)
| + | |
| - | * M116 (pSB1A2+''glgC''-mut1,2) and M120 (BABEL2+''glgC''-mut1,2,3) submitted for sequencing. (CF)

Also resubmitted M109 (pSB1A2+crtBI) for sequencing using both forward and reverse primers, because I realised that yesterday I circled BigDye rather than "reaction required" on the sequencing form\! (AH)
| + | |
| - | * Made culture of pSB1A2+CrtE from plate 118, which was subcloned from plate 116 for minipreps (1-4) (YAN & HX).
| + | |
| - | * Transformation of L39 (Cex+Edinbrick1) into *plate 121/122;* and L40 (CenA+Edinbrick1) into *Plate 119/120.* (YAN).
| + | |
| - | * Digested and ligated M63 (crtE) and M72 (dxs). for M63 i used buffer H, XbaI, and PstI, For M72 i used buffer B, SpeI and PstI. M63 in inserted downstream of M72. the DNA samples of M63 and M72 were taken from the gel after using SYBR-Safe staining. (OG)

| + | |
| - | | + | |
| - | h5. Friday 15 August 08
| + | |
| - | | + | |
| - | * Plates from yesterdays transformations of pSB1A2\+_cex_ and pSB1A2\+_cenA_ (119-122) failed to show any signs of growth. The transformation's being repeated. (AH)
| + | |
| - | * Glycogen assay performed: Flooding colonies with Gram's iodine solution yields results after \~5 minutes. Colonies on the (+)glucose plate stained darker than those on the (-)glucose plate (brown compared to no apparent change). The staining seems to grow more apparent up to \~30 minutes and then fades to nothing as the plate dries off. (AH)
| + | |

| + | |
| - | * PCR of M43 (repeat: glgC mut 1+2 -->- *{-}P71A{-}*\-), M120 (repeat: glgC mut 1+2+3 \--> *P72*), and rrnB from the four _C. fimi_ genomic DNA preps made yesterday plus the original prep as a positive control (*P73~77*). PCR products run on *Gel 54*. Results: P71A and P72 succeeded, producing large quantities of DNA around the length of glgC; P74 yielded a single band around 1.5~2 kbp whilst P73 and P75 yielded gel-length smears and nothing came of P76 and P77 (the control).
