  • Efficiency of EDC mediated coupling is increased in the presence of Sulfo-NHS
  • Amine reactive Sulfo NHS esters can be created on any carboxyl containing molecule
  • Sulfo NHS derivatives are water soluble, so crosslinking can be done in physiologic solutions
  • High purity, crystalline Sulfo NHS can be used to create high purity activated derivatives
