Things we did today
Wetlab work
Test of lab's RE (cont.)
- Grace
- Ran RE digests from yesterday on a 1.2% agarose gel
- BamHI and HindIII digested DNA not visualized. Too little DNA added?
- NotI works. All plasmid preps except I14032 resulted in 2 bands of the correct size.
- Note: There is genomic DNA in all preps (band that looks like fire up top)
Verified transformants
- Grace
| Construct | Colony forming units |
|---|---|
| GFP+B0015(tt) | 1 |
| GFPf+B0015(tt) | 52 |
| slr1+GFPf | 56 |
| pilA+GFPf | 43 |
- Colony PCR of transformants to check for correct insert
- GFP+tt = unsuccessful
- GFPf+tt colonies 1, 3, 5 good
- slr1+GFPf colony 5 potentially good
- pilA+GFPf colonies 1, 2, 3, 4 potentially good
- Ligated slr, pilA with GFPf (ES digested) instead of GFPf (XP digested). Still got colonies, some which are potentially good. Hm...
- Restreaked:
- GFPf+tt colony 5
- slr1+GFPf colony 5
- pilA+GFPf colonies 1 and 4
- Will colony PCR again tomorrow to prep for sequencing
3A assembly
- Grace
- Ligated p+r with g or s onto pSB1A2
- pnir+rbs with GFP, slr1, pilA
- plac+rbs with GFP, slr, pilA
- Transformed into DH5α using 5 μl ligation reaction
Rear ligation of signal sequences and GFPf
- Grace
- Ligated slr and pilA with XbaI and PstI digested GFPf
- Transformed into DH5α using 5 μl ligation reaction
Drylab Work
Sequencing
- Grace
- Downloaded sequences from CORE Hawaii. Began assembling contigs and checking sequences.
