Thermo Scientific™ Pierce Sulfo-NHS is pure N-hydroxysulfosuccinimide, the essential compound needed to prepare water-soluble, amine-reactive NHS-ester crosslinkers or to enhance conjugation efficiencies when using the carbodiimide EDC.

Highlights:

  • Forms an acyl amino ester with carboxyl groups when used with the EDC
  • Sulfo-NHS-activated molecule reacts efficiently with primary amines, resulting in stable amide bond
  • Allows for two-step EDC reactions between carboxyl- and amine-containing molecules
  • Sulfo-NHS-activated molecule can be stabilized by drying, allowing manufacture of amine-reactive probes and surfaces
  • Reactive groups: Sulfo-NHS
  • Reactive toward: amino groups (upon activation of carboxylates)
