4-APB, SE, TFA is heterobifunctional crosslinking reagent. The succinimidyl ester is reactive with primary amines on peptides, proteins, modified nucleotides, biopolymers and other amine containing biomolecules and yields a robust amide linkage. The aromatic amine group may be used as a nucleophile in conjugation reactions or may be activated to an isothiocyanate, an isocyanate, or may be diazotized to synthesize a reactive crosslinker. .
