DSG crosslinker (Disuccinimidyl glutarate; Di(N-succinimidyl) glutarate) is a homobifunctional crosslinking reagent that is membrane permeable. DSG protein crosslinker is often used in ChIP assays to determine DNA-protein binding interactions; using DSG and formaldehyde in a two-step cross-linking strategy greatly improves the ChIP assay.DSG crosslinking takes place through amine-reactive NHS esters at both ends of a 5-atom (7.7 angstrom) spacer arm. DSG crosslinker must be dissolved in an organic solvent, such as DMSO or DMF, then added to an aqueous crosslinking reaction. The directly water soluble version of Di(N-succinimidyl) glutarate (DSG) is BS2G.
