What is 4-MALEIMIDOBUTYRIC ACID?
Description
4-(2,5-dioxo-2H-pyrrol-1(5H)-yl)butanoic acid contains a maleimide group and a terminal carboxylic acid. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol.
