WebChromatin immunoprecipitation, or ChIP, is an antibody-based technology used to selectively enrich specific DNA-binding proteins along with their DNA targets. ChIP is used to investigate a particular protein-DNA … Webpreparation). As such, more targets are identified with ChIP-seq and only the top ChIP-seq targets will generally validate using ChIP-chip. For qPCR, it is recommended that 24-48 targets be selected from a range of p-values. At least six must be negative control regions where no significant enrichment is indicated by the ChIP-seq or ChIP-chip data.
