BS2G Crosslinker, or 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 can be used to label cell surface proteins.
