Chip fold change

WebFold change is a measure describing how much a quantity changes between an original and a subsequent measurement. It is defined as the ratio between the two quantities; for quantities A and B the fold change of B with respect to A is B/A.In other words, a change from 30 to 60 is defined as a fold-change of 2. This is also referred to as a "one fold … WebAug 13, 2007 · The experiment is done on 400 µl of sonicated DNA. I take 20 µl for Input, 180 µl for ChIP and the last 180 µl for the ChIP negative control (immunoprecipitated with normal Rabbit IgG). After DNA isolation, I perform quantitative PCR on 20 ng for the input, the ChIP and the negative control.
