N-Succinimidyl maleimidoacetate

White Crystalline Solid

A hetero-bifunctional cross-linking reagent for the preparation of protein-protein or protein-hapten conjugates.

Maleimidoacetic acid N-hydroxysuccinimide ester is a crosslinking reagent that contains NHS ester- and maleimide-reactive groups at the opposite ends of a 4.4 ? spacer arm. This configuration allows for sequential, two-stage conjugation with amine and sulfhydryl functional groups in the preparation of protein-hapten or protein-protein conjugates.
