Sulfo-SMCC crosslinker (Sulfosuccinimidyl-4-[N-maleimidomethyl]cyclohexane-1-carboxylate) is a water soluble, heterobifunctional crosslinker (SMCC is the water insoluble protein crosslinking analog of Sulfo-SMCC crosslinker). As such, the non-membrane piercing Sulfo-SMCC protein crosslinking reagent can conjugate extracellular proteins.

Sulfo-SMCC crosslinker has an 8.3 angstrom, non-cleavable spacer arm. Sulfo-SMCC conjugation occurs via a maleimide group which reacts with sulfhydryls (thiols, -SH), while its Sulfo-NHS ester is reactive toward primary amines (as found in Lysine and the protein or peptide N-terminus). Sulfo-SMCC crosslinking reagent is routinely used to prepare hapten-carrier protein and antibody-enzyme conjugates, such as HRP conjugation.
