Performing Quantitative PCR after Chromatin Immunoprecipitation (ChIP) of

Chromatin immunoprecipitation (ChIP) is a technique used to study specific protein-DNA interaction. Briefly, in this technique, antibodies to proteins of interest are used to isolate regions of DNA where these proteins bind. ChIP samples can be processed and analyzed in different ways. One of the approaches for assessing the results of ChIP experiments is quantitative PCR (qPCR). qPCR is used to quantitatively measure the amount of DNA fragments that have been isolated, reflecting the signal of specific proteins interacting with these fragments. This protocol describes both the "percent input" method and the "fold enrichment" method for ChIP-qPCR data analysis using
