Overview

QuikChange transformation results:

  • Negative control (QuikChange on pWhitescript, no DpnI treatment): about 350 colonies, mostly white, maybe 25 blue
  • positive control (QuikChange on pWhitescript, DpnI treated): 34 colonies, 23 blue
  • EM7:ZeoR_v0120: about 2 dozen colonies
  • MV8: about 1 dozen colonies

QuikChange efficiency is about 68%. Picked 8 colonies from each sample plate and set up liquid cultures and streak plates. Today I'm performing 'colony' PCR on the streak plates and then running them on a gel. For the samples that look good (have product in the right size range), I'll do PCR cleanup and submit for sequencing, as well as perform plasmid preps on the pellets of the liquid cultures.

Gel Verification

For EM7:ZeoR_v0120, colonies 1, 2, 3, 4, 5, and 7 have the correct size insert (~700 bp). For MV8, colonies 2, 3, 5, 6, 7, and 8 have the correct size insert (~440 bp). Will perform PCR clean-up on all successful PCR products and send 3 from each type of plasmid out for sequencing by the core lab.

Sequencing Results (2016-02-03)

Got the sequences back for the MV8 samples, they all look terrible. Going to try miniprepping and submitting plasmids instead.
