Padlock Probe Concentration Test using Med Conc (100nM) Fixed Template

  • Previously fixed 1nM template resulted in almost no rolonies
  • 96-well plate PGP1f Cells
    • Fixed 12/26/13 and RT with 12/30/13
    • Using wells C7-C10, F3-F10
      • Marked 1 position for each well (adapter clips on bottom&right)
      • .maf file saved in 3-31-2014
  • Test padlock probe concentrations NegCtrl-0pM, 10pM, 50pM, 100pM, 1nM, 10nM
