Dimethylmaleic anhydride, a specific reagent for protein amino groups.


PMID 2713129

Abstract

The reagent dimethylmaleic anhydride does not cause a stable modification of thiol compounds under the conditions used for modification of protein amino groups, in contrast to maleic and monomethylmaleic anhydrides, which produce an irreversible modification of sulfhydryl groups. This behavior and the low reactivity toward hydroxyamino acid residues, shown in a previous work, make dimethylmaleic anhydride a specific reagent for protein amino groups.
