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.


Features:

  • Efficiency of EDC-mediated coupling is increased in the presence of Sulfo-NHS
  • Amine-reactive NHS esters or Sulfo-NHS esters can be made with any carboxyl-containing molecule
  • Sulfo-NHS derivatives are usually directly water-soluble
  • Greater than 95% by quantitative NMR; average lot purity is greater than 99%
