Description
General Description
PMPI is p-maleimidophenyl isocyanate, a maleimide-and-isocyanate crosslinker for attaching compounds to sulfhydryl groups of cysteines after conjugating the linker to hydroxyl groups on a molecule by urethane (carbamate) bonds. The Maleimide group of PMPI reacts with sulfhydryl groups to form stable thioether linkages and Isocyanate reacts with non-aqueous hydroxyl groups to form carbamate linkage. It is an excellent tool for conjugating hydroxyl-containing compounds such as steroids and vitamins, but targets and reaction solutions must not contain primary amines.
