June 30th, Saturday

  • Took PCR out of thermal cycler at 9:00 am (DPW)
    • Set up gel using NEB 100bp and 2-log ladders (10:00am)
    • Gel extracted PCR product, quantified at ~10ng/uL
    • Set up new Phusion PCR using Gibson 1 as template
      • Dylan's magic three-anneal method (57.6/65/72)
      • Extension time of 3 min.


  • Continued gel extraction of p21 PCR digest from previous day (SS)
