Probes, Target and Ampligase Buffer Mix
- gDNA: 12878 (80.3ng/ul)
- First strand cDNA from HBRR
- CA12k_Nov2014 Probes
- V4 819nM x (150nt*325Da/nt + 79Da) x 10^-6 L/ul = 40.0 ng/ul
- V7 768nM x (150nt*325Da/nt + 79Da) x 10^-6 L/ul = 37.5 ng/ul
- Diluted 1:2 with H2O for easier pipetting (final conc 20.0ng/ul and 18.75ng/ul)
- NTC is the NTC from first strand cDNA synthesis
- 5nM of each supp oligos (5 x 10^-6 nmol/ul)
- 100-fold more of each suppressor oligo = 1.5385 x 10^-14 mol = 15 x 10^-6 nmol

- Sample 4, accidentally added an extra 9ul H2O so added 4ul 10X Ampligase Buffer
- Added 4ul of AmpLigase enzyme mix as well (vs 3ul for others)
- Add 40ul mineral oil on top
Program
- 95C 30sec -> cool down to 55 C at 0.02C/sec -> 55 C 20h
- -> add 3ul AmpLigase enzyme mix (0.5U/ul AmpLigase in 1X AmpLigase buffer)
- -> 55 C 20h-> 94C 2min -> add 2ul Exo I/III mix-> 37C 2h -> 94C 2min -> 4C hold.
