Results: ADD IMAGE

  • mms6 was not amplified
  • RFP was amplified
    • Expected size is ~800bp
    • Actual size is >1000bp
      • We believe that the suffix segment of the fusion primer annealed rather than the FP segment. This would cause the promoter (R0040) of J04450 to be amplified, adding ~200bp, giving a final size of >1000bp.

Objective: Confirm assembly (3 antibiotic) of K118021 and B0015 from Sept. XX, 2010 via PCR.
Method: Set up 50uL reaction mixture with 2uL of ligated DNA. Used VF2 and VR primers.
