Sulfo-NHS (N-Hydroxysulfosuccinimide sodium salt)

Pierce™ Sulfo-NHS (N-hydroxysulfosuccinimide) is a chemical modification reagent for converting carboxyl groups to amine-reactive NHS esters for bioconjugation, crosslinking, labeling and immobilization methods.

  • Improve efficiency of EDC coupling reactions
  • Water-soluble and membrane-impermable
  • Activate nanoparticles with amine-reactive Sulpho-NHS esters
  • Crosslink proteins to carboxyl-coated beads or surfaces more efficiently

Sulfo-NHS (N-hydroxysulfosuccinimide) enables control and modification of carbodiimide crosslinking reactions involving activation of carboxylates (—COOH) for conjugation with primary amines (—NH2). Derivatives are easily synthesized by mixing the Sulfo-NHS with a carboxyl-containing molecule and a dehydrating agent such as the carbodiimide EDC (EDAC). The method is the basis for generating many types of protein labeling reagents, including amine-reactive fluorescent dyes, biotin affinity tags and pegylation compounds.
