Things we did today

Wetlab work

Test of lab's RE (cont.)

EtBr stained 1.2% agarose gel ran at 72V for 1.5 hours. Thirty microliters of RE digest reaction were loaded into each well.
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
EtBr stained 2% agarose gel ran at 95V for 1 hour. Five microliters of PCR reaction were loaded into each well.
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

[[Editing Team:Hawaii/Notebook/2008-08-11|Transformation

Margaret

  • Re-streaked yesterday's transformation
  • Colony PCR on each of the re-streaked colonies

Construction of Omega Interposon

Margaret

  • Digested pSMC121 and pSB1A2 with SmaI
  • Ligated parts together (over-night ligation)

Plasmid Prep

Margaret

  • B0015, B0030, E0040, J33207
  • Drying in hood

Glycerol Stock

Margaret

  • oriT (3 bottles) and I14032 (1 bottle)

Media Making

Margaret

  • Amp100 plates, Solution 3 for plasmid preps, 100mM IPTG(look in -20C with the antibiotics)

Drylab Work

Sequencing

Grace
  • Downloaded sequences from CORE Hawaii. Began assembling contigs and checking sequences.

Discussion
