Description and Uses

6-Maleimidocaproic 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.

6-Maleimidohexanoic acid is used as a probe for introducing maleimides groups into biomolecules and active pharmaceutical ingredients. Further, it is used with N-hydroxysuccinimide ester as a bifunctional cross-linking reagent. In addition to this, it acts as a probe for thiol groups in membrane proteins.
