Application
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.
Analysis Note
Absorption spectra shows a maximum at 453 nm (in methanol). After reaction with butylamine: max. absorption at 428 nm (Lit.)

A general scheme for obtaining a fluorescent donor/acceptor peptide substrate via solid-phase synthesis methodology is presented. The key feature of this method is the design of a glutamic acid derivative that has been modified on the carboxyl side chain with

A series of new substrates for determining the catalytic activity of cysteine proteinases is described. The rate of hydrolysis by papain was monitored by a fluorescence continuous assay based on internal resonance energy transfer using 5-[(2-aminoethyl)amino]naphtalene-1-sulfonic acid (EDANS) and 4-(4-dimethylaminophenylazo)benzoic
