  • Ideal crosslinker for enzyme labeling of antibodies, both enzyme activity and antibody specificity can be preserved
  • Create specific bioconjugates via one- or two-step crosslinking reactions
  • Create sulfhydryl-reactive, maleimide-activated carrier proteins for coupling haptens

  • Amine reactive Sulfo NHS ester crosslinks rapidly with primary amine-containing molecule
  • Sulfhydryl-reactive maleimide reacts with cysteine residues to yield specific conjugates
  • Sulfo SMCC is water soluble, so crosslinking can be done in physiologic solutions
  • High purity, crystalline Sulfo-SMCC can be used to create high-purity maleimide-activated derivatives
  • Cyclohexane bridge confers added stability to the maleimide group making Sulfo SMCC the ideal crosslinking agent for maleimide activation of proteins.
