Repeat CES22k SNP capture

I decided to repeat the circularization reaction with a slightly different protocol. The reason is that I found the results from the PGP1L-011507 experiment was quite good. My hypothesis is that if the poor efficiency is due to the probes anneal to non-specific targets and get extended from the 3'-end, then adding KLN mix later will give more time for the probes to find their targets.

Circularization

  • dscDNA: 100ng per reaction, gDNA:Probe=1:200.
  • dNTP: 2x theoretical number of circles = 1pmole/10ul = 100nM.
  • Probe: CES22k, 06/05/08, 525nM.
  • KLN mix:
    • Titatium Taq: 2U/ul
    • AmpLigase: 0.5U/ul
    • dNTP: 1uM (each)
Template 10x buffer CES22k H2O
