Things we did today

Wetlab work

Verification of Transformants

Grace
File:101008colonypcr.jpg
EtBr stained 2% agarose gel ran at 95V for 1 hour. Two microliters of PCR product were loaded into each well.
Construct Colonies
nir+rbs+GFP+tt#1 100

BBpRL1383a lawn
(-) no DNA 0
  • Colony PCR of transformants

Overnight RE digest

Grace
  • EcoRI/PstI:
  • BBpRL1383a-1
  • nrsg #6 (PCR)
  • prpgt #5, 7, 11 (PCR)

Triparental Conjugation

Grace
  • Began triparental conjugation between E. coli containing RP1 and BBpRL1383a -1 or -18 and Synechocystis
  • RP1 OD600=0.6341
  • BBpRL1383-a OD600=61.25
  • BBpRL1383a-18 OD600=0.4884
  • Synechocystis OD700=0.8629, OD730=0.7337
  • Placed plates in SC 37C CO2 incubator until Monday

Verification of plasmids

MARGARET
Verification of plasmid preps and digests.
  • Why haven't I gotten good efficiency of transformation? I ran a gel of the plasmids i am working with and got the answer. Apparently there was a mix-up and I was using low quality plasmid.
  • The pSB1A3 and pSB3K3 digested and de-phosphorylated (lanes: ) were thrown out. Norman's pSB1A3 and pSB1A7 were digested with E and P today at 4:30pm.
  • The base vector is digested--> bands appear to be correct size.
