英文名稱:6-Maleimidohexanoic acid N-hydroxysuccinimide ester
CAS #: 55750-63-5
簡介:N-(e-Maleimidocaproyloxy)succinimide ester (EMCS) is a non-cleavable, water insoluble, hetero-bifunctional crosslinker that is commonly used to crosslink haptens to carrier proteins and en-zyme to antibody. The EMCS crosslinker spacer arm is longer than GMBS. The EMCS NHS es-ter and maleimide reactive groups react with amino and sulfhydryl moieties, respectively.
Application
A heterobifunctional cross-linking reagent incorporating an extended spacer 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) The second coupling is 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. Contains 9 atom linker. An extended aliphatic spacer stabilizes the maleimide prior to coupling compared to aromatic spacers.
