The Uses of 4-((4-(DIMETHYLAMINO)PHENYL)AZO)BENZOIC ACID, SUCCINIMIDYL ESTER
4-[4-(Dimethylamino)phenylazo]benzoic acid N-succinimidyl ester is a useful reagent (similar to MANCYL-SE) for labeling proteins or peptides through their amino-groups by forming stable peptide bonds. The succinimidyl ester is reactive with terminal amines or lysines of peptides and other nucleophiles for fluorescent studies of proteins. Its fluorescent properties (has a characteristic broad and intense visible absorption but has no fluorescence) make it an ideal long wavelength quencher and it has been utilized as an acceptor chromophore in FRET studies. It is also used for N-terminal modification of peptides in automated synthesis.
