      • 72 degrees for 5 minutes
    • Initially ran on 2% E-gel, but could not see library/template. Re-ran samples on 1% agarose gel.

1) 2 uL 100 bp low scale ladder, 2) 1 uL DNA template, 3) 5 uL PCR product

→Visible amplification, but size range difficult to discern.

  • Re-run PCR to improve visibility and get more amplification (2015-08-27)
    • Mix:
      • 10 uL DNA
      • 25 uL NEBNext High Fidelity 2x PCR Master Mix
