WebSep 7, 2024 · A crucial part of determining ChIP enrichment at a genomic locus by qPCR is the use of valid controls. It is standard to perform PCR with control DNA in parallel, which can either be derived from an aliquot of the sonicated chromatin before the IP (‘input control’), or DNA from a mock ChIP performed with an IgG control antibody or an ...

The location in the peak with the highest fragment pileup, hereafter referred to as the summit, is predicted as the precise binding location. The ratio between the ChIP-seq tag count and λlocal is reported as the fold enrichment. WebNov 14, 2013 · These measures will detect several possible failure modes of ChIP-seq: insufficient enrichment by immunoprecipitation step, poor fragment-size selection, or insufficient sequencing depth. ... or the fold enrichment.
