Week Seven

Monday, 7/28/14

• Ran colony PCR on pTG002/3/6-transformed JM109 cultures grown up over the weekend. Bad results for all of them
• Created and ordered new primers that will hopefully avoid secondary-structure-formation when the exonuclease attacks the 5' end during Gibson assembly.

• Single-transformations run on each of the constructs used in the double-transformations:
  1. pMB001
  2. pMB002
  3. pMB003
  4. pMB004
  5. pMB005
  6. pMB006

• Colonies were picked from pAA008 transformations incubated over the weekend, as well as the pAA009 & pAA010 transformations, which had been set up last Thursday.
• Set up liquid cultures of the colonies to grow overnight in preparation for miniprep and sequencing tomorrow

Tuesday, 7/29/14

• Ran Gibson assembly products on a gel. Results inconclusive
• Started 3 mL liquid cultures of bacteria (with pTG004 & pTG005) with varying levels of aTc induction:
  • 0 nM, 50 nM, 150 nM, 250 nM, 350 nM, & 450 nM

• Colony PCR was run on several of the colonies that emerged from the single-transformations last night
• Gel was run, but wrong primers were used. New primers for sequencing/colPCR were ordered, and colPCR will be redone tomorrow.

• Miniprepped liquid cultures grown last night and shipped samples for sequencing.

Wednesday, 7/30/14

• Analyzed sequencing results:
  • pAA008 successfully constructed
  • Minipreps supposedly containing pAA009 & pAA010 instead contain pKS001 backbone template
• We redid PCR of the pAA009/010 backbone
• DpnI digestion for 2 hours, followed by PCR purification. The purified product was then run on a gel.
