Probe Capture Plan
- From [1] and [2]: ~37.4 pmol (2.35 ug) in 140ul
- Use HAPMAP (ID C1) gDNA (87ng/ul) as template/target
- Use a probe:target ratio of 100:1
- Hosuk wants to use some circularized oligos to generate rolonies
- Hosuk said there are about 3,000 cells per dish, I will round up to 10,000 so there are extra oligos for multiple experiments
10^4 cells x 10^4 rolonies/cell = 10^8 rolonies in dish
If we assume 50% of targets in reaction can assist circularization we need 2*10^8 targets = 3.32*10^-16 mol
At 100:1 that means we need 3.32*10^-14 mol of probes = 2.56*10^-18 mol of probe sets
Therefore the reaction set up below should be sufficient
100:1 Probe:Target Calculations
Probe set size | 12964 | probes |
gDNA template | 300 | ng |
gDNA MW | 1.95E+12 | g/mol (3x10^9 bp x 650 Da/bp + 157.9 Da) |
template | 1.5385E-19 | mol |
probe sets (100:1) | 1.5385E-17 | mol |
probe MW (12,964 probes, 193nt) | 814190000 | g/mol (12,964 probes x (193 nt/probe x 325 Da/nt + 79 Da)) |
