Maleimide-PEG-amine, MW 20,000 is a linear heterobifunctional PEGylation polymer. The NH2 group is reactive with carboxylic acids (in the presence of HATU or EDC) or activated NHS esters via formation of amide linkage. The maleimide group can react with a thiol group to form a covalent thioether bond. Reagent grade, for research purpose.
