N-Hydroxysulfosuccinimide sodium salt, 97%, Thermo Scientific Chemicals

N-Hydroxysulfosuccinimide sodium salt is used as crosslinking agents for preparing hydrophilic active esters. It is also used to activate carboxylic acids to the more reactive succinimidyl esters for coupling, biotinylation and conjugation with fluorophores. Further, it acts as a hydrophilic ligand and also used in covalently binding proteins to carboxyl containing beads, resins, other nanoparticles. It is involved in the conversion of carboxyl groups to primary amine-reactive sulfo-NHS esters.
