BS2G crosslinker (BS2G; Bis[Sulfosuccinimidyl] glutarate) is an amine-reactive, water soluble, homobifunctional protein crosslinker. The BS2G protein crosslinker"s 5-atom (7.7 angstrom) spacer arm is non-cleavable and the molecule is not cell membrane permeable. The BS2G crosslinking reagent"s Sulfo-NHS esters are amino reactive and can be used to label cell surface proteins.Also, the Sulfo-NHS esters of BS2G allow the crosslinking reaction to occur in aqueous solutions in near physiological conditions. DSG (Disuccinimidyl glutarate; Di(N-succinimidyl) glutarate) is the membrane permeable analog of BS2G.BS2G is the light version (BS2G-d0), whereas BS2G-d4 is the heavy, deuterated analog and together they can be used for protein-protein interaction mapping using Liquid ChromatographyMass Spectrometry (LCMS, LC/MS, LC-MS).
