WebThe principle of ChIP is simple: the selective enrichment of a chromatin fraction containing a specific protein. An antibody is used to immunoprecipitate a protein of interest together with its associated DNA. It is then recovered and analyzed for example by PCR, microarrays or sequencing to find out at what genomic loci the protein was bound to. WebFragmentation ensures that protein/DNA complexes in high–molecular-weight chromatin are soluble and accessible to your ChIP antibody.
