Overview

Maleimide PEG acid (Maleimide-PEG-COOH) is a thiol reactive heterobifunctional PEG derivative. Maleimide groups react with sulfhydryl groups at pH 6.5~7.5 at room temperature to form stable thioether bonds, while carboxylic acid groups on the other end can react with amine and acid amine reactive molecues.
