Chemical Structure

Description	N-Ethyl-[d5]-maleimide is the labelled analogue of N-ethylmaleimide. N-Ethylmaleimide (NEM) is a derivative of maleic acid and is used as a reagent for alkylation and covalent modification of nucleophilic thiol residues on proteins. It acts as an irreversible inhibitor of all cysteine peptidases that alkylates the active site thiol group of the enzymes.
