Things we did today

Wetlab work

Verification of Transformants

EtBr stained 2% agarose gel ran at 95V for 100 min. Five microliters of PCR reaction were loaded into each well.
Grace
Construct Colony forming units
slr1 + GFPf 69 + 1 cluster of colonies
pilA + GFPf 17
nir+rbs + GFP 0
nir+rbs + slr1 0
nir+rbs + pilA 1
plac+rbs + GFP 0
plac+rbs + slr1 0
plac+rbs + pilA 0
  • Colony PCR of transformants and restreaked colonies from yesterday
  • Ran on 2.5% agarose gel at 95V for 100 min.
  • Restreaked:
  • slr1+GFPf colony 5
  • pilA+GFPf colony 4
  • GFPf likely J33207 due to mix up -- see below

Wetlab work

Plasmid Prep

Margaret

  • OriV1-4 and aadA(BB) 4 **the only correct transformants from yesterday's ligation/transformation

Ligation

Margaret

  • I corrected my math from yesterday's ligation and re-did the ones that did not ligate correctly

Transformation

Margaret

  • omega ligation from yesterday
  • rep+B0030, P1+B0015, aadA(pRL1383a) +B0030 from today's ligation

Gel From Yesterday's Colony PCR

Margaret

Drylab Work

Sequencing

Grace
  • Checked sequencing results returned from CORE Hawaii
  • Confirmed:
  • B0015
  • B0030
  • B0034 (one bp off)
  • nir
  • slr
  • slr1 = slr2 huh?
  • Other:
  • nir+rbs
  • No rbs present; only nir
  • Huh? We ligated nir INTO rbs
  • I14032+rbs
  • No plac present; only rbs
  • BB-pRL1383a
  • E0040 (GFP) went in successfully, not J33207
  • WTF? Our plasmid preps were/are mislabeled
  • Redo ligation to get blue/white screen?
  • GFP+tt (reverse only)
  • Low quality read; GFP is not present (segment too small)
  • GFPf+tt (reverse only)
  • lacZ fragment present; no tt
  • Huh? We ligated the part INTO tt
  • GFPf+tt and J33207+tt samples switched?
  • J33207+tt
  • Part did not go in; tt only
