WebUse chromatin immunoprecipitation (ChIP) to detect and relatively quantify specific protein-DNA and protein-protein interactions in vivo at a single locus or multiple loci. ... (chromatin-protein) are then sheared into ∼500 bp DNA fragments using either enzymatic digestion or physical shearing by sonication. The DNA-protein complexes are then ... WebMay 22, 2016 · Enzymatic shearing is essential when carrying out native ChIP (chromatin which has not been cross linked) as sonication can disrupt the protein/DNA complexes. Certain cell types may be resistant to lysis resulting in poor enzymatic shearing efficiency in this instance try sonication which aids in both shearing and lysis of the cells.
