"WebN-Ethylmaleimide (NEM) is an alkylating reagent that reacts with sulfhydryls. At pH 6.5-7.5, the maleimide reaction is specific for sulfhdryls; however, at pH values greater than 7.5, reactivity with amino groups occurs. Maleimide groups react with sulfhydryls by nucleophilic attack of the thiolate anion on one of the carbons of the double bond. " - Thiolate anions
