Description

Thermo Scientific Pierce EMCA is a carboxylic acid compound with a terminal maleimide group that can modify proteins and other molecules by EDC-mediated and sulfhydryl-targeted conjugation.

Features EMCA:

• Convert sulfhydryl groups to carboxyl groups for conjugation to amines via carbodiimide (EDC)
• Prepare maleimide-activated proteins using EDC to modify primary amines
Maleimides react with—SH groups at pH 6.5-7.5, forming stable thioether linkages

EMCA (N-epsilon-maleimidocaproic acid) is a heterobifunctional crosslinker that reacts with sulfhydryl groups to present a terminal carboxyl group. Additionally, the carboxyl can be coupled to amine-containing molecules using the water-soluble carbodiimide EDC. The EDC reaction results in an intermediate ester, which can react with primary amines to form amide bonds. Thus, amine-containing molecules can be modified to contain sulfhydryl-reactive maleimides.
