Calculations
Probe: Target ratio is 100:1 The mass of one genome is 3pg: 200ng of DNA is equal to 200ng/3pg. The amount of probe needed is 200ng/3pg * 250 for each target, and the total amount of probe is (200ng/3pg * 100 * 46417)/(6.0 * 10^23) Example Assume the concentration of probe Jan09-1 to be 10ng/ul. Knowing the length of the probe is ~100 bases and 1 base = 330 Daltons (1bp = 2 bases = 660 Da). Solve: Concentration of Jan09-1 probe: 10ng/ul / 33000 = 303 nM Volume of probe needed= (200ng/3pg * 100 * 46417)/(6.0 * 10^23 * 303 nM) = 1.73ul
Volumes needed of each sample: Sample 1 – 200ng / 102.7ng/ul = 1.947ul
Sample 2 – 200ng / 183.4ng/ul = 1.091ul Sample 3 – 200ng/ 100.0ng/ul = 2.000ul Sample 4 – 200ng/ 200.0ng/ul = 1.000ul Sample 5 – 200ng/ 58.9ng/ul = 3.396ul Sample 6 – 200ng/ 55.9ng/ul = 3.578ul Sample 7 – 200ng/ 89.4ng/ul = 2.237ul Sample 8 – 200ng/ 99.7ng/ul = 2.006ul
