Colony PCRs

  • Gel from 7/8/07
  • Ran a gel of the overnight Colony PCR's
  • L to R: Ladder; T9002-3K3 (4,3,2,1); I2055-1AK3 (1,2,3,4); E0240-3K3 (4,3,2,1); E0240-1AK3 (1,2); Ladder
  • T9002 was to check if it is scarred, I2055 was to see if it is constructed (religation, not pcr-ing promoter), both E0240's scarred
  • T9002 should be over 2kb but shows as only 400bp
  • I2055 looks the right size (except for #2 which I probably messed up)
  • E0240-1AK3 looks fine but 3K3 is also about 500bp
  • Most likely 3K3 is the problem
  • Made overnights of each type to prep for sequencing tomorrow
  • Also overnighted 3K3 plasmid from original registry plate

I2055 w/ PCRed in Promoter

  • Heat Shocked overnight double digest with Mfe1 and Nsi1
  • Ligated with 1AK3
  • Transformed 3ul of ligation and plated on Kan
  • Started to ligate with 3K3 but since 3K3 is acting up, was discarded


  • Overnights in LB and Tet worked
  • Strange, must have somehow lost Amp resistance
  • Made a glycerol
  • Minipreped w/ 8.5 water for sequencing and w/ EB
