NHS-diazirine has not been tested for cross-linking in a ChIP application. EGS (Cat. No. 21565) and DSG (Cat. No. 20593) are not used by themselves in ChIP, but rather in combination with formaldehyde. While formaldehyde is good for crosslinking proteins that are in direct contact with DNA, it cannot trap proteins that may be bound in a complex with other proteins but are not in direct contact. Thus EGS or DSG can cross-link proteins to proteins that are in direct contact with DNA and are crosslinked to it by formaldehyde. See this reference for more information
