Application

N-Hydroxysuccinimide (NHS) can be used in the following applications:
  • To synthesize N-succinimidyl 3-(2-pyridyldithio)-propionate, a heterobifunctional reagent useful for protein-protein conjugation and also to incorporate aliphatic thiols into proteins.
  • To synthesize NHS esters of long-chain fatty acids.
  • NHS can activate the phosphonic acid monolayers immobilized on titanium surface for binding with proteins.
