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 crosslinking strategy greatly improves the ChIP assay. Disuccinimidyl crosslinkers include disuccinimidyl glutarate (DSG), disuccinimidyl suberate (DSS), and bis-N-succinimidyl-(pentaethylene glycol) ester (BS(PEG)5)[1]. DSG crosslinking takes place through amine-reactive NHS esters at both ends of a 5-atom (7.7 angstrom) spacer arm. DSS (crosslinker arm length = 11.4Å), DSG (crosslinker arm length = 7.5Å), and disuccinimidyl tartrate (DST, crosslinker arm length = 5.8Å) are homobifunctional crosslinking reagents that react specifically with primary amines[2]. DSG crosslinker must be dissolved in an organic solvent, such as DMSO or DMF, and then added to an aqueous crosslinking reaction. The directly water-soluble version of Di(N-succinimidyl) glutarate (DSG) is BS2G.

개요Disuccinimidyl glutarate (DSG) is a homobifunctional crosslinking agent that contains amine-reactive N-hydroxysuccinimide (NHS) ester groups at each end. DSG is membrane-permeable and non-cleavable. DSG can be combined with formaldehyde fixation to improve the detection of specific protein-DNA complexes.

용도Disuccinimidyl glutarate is used as a membrane-soluble, amine-reactive N-hydroxysuccinamide ester-based homobifunctional crosslinking reagent. It is a homobifunctionla cross-linking reagent, for ex. isolation of the insulin receptor.
