Description

Application

6-Maleimidohexanoic acid N-hydroxysuccinimide ester is a heterobifunctional cross-linking reagent with amine and sulfhydryl reactivity. Typically, coupled initially to molecules containing primary amines by amide bonds buffered at pH 7.5 (6.5-8.5). Second coupling specific for molecules containing free sulfhydryl by thioether linkage buffered at pH 6.8 (6.5-7.0). Useful for preparation of enzyme immunoconjugates and hapten carrier molecule conjugates.

Packaging
