文献和实验How to Make Simple Solutions and Dilutions
= 200 ul = 0.2 ml C2 = the new concentration = 25 mg/ ml By algebraic rearrangement: V1 = (V2 x C2) / C1 V1 = (0.2 ml x 25 mg/ml) / 100 mg/ml and after cancelling the units, V1 = 0.05 ml, or 50 ul
, resuspend in 2 ml 1 x LiAc/ 0.5 x TE incubate at RT for 10 min combine in tube: 100 µl cells, 10 µl salmon sperm DNA (10 mg/ml), up to 15 µl DNA to be transformed add 700 µl 1 x LiAc / 1 x TE / 40 % PEG mix incubate for 30 min
