Application

AMCA-NHS has been utilized in the development of a donor europium chelate fluorochrome for use in LRET based analyses by first reacting with an amino group and then with DTPA anhydride . Utilized in FRET based studies, acting as the donor dye and can be paired with fluorescein-5-isothiocyanate as the acceptor dye . A blue fluorescent dye reactive towards primary amine groups on proteins, peptides, antibodies, and other biomolecules (at pH 7.0-9.0).

Packaging

The (Ca(2+)-Mg2+)-ATPase of sarcoplasmic reticulum was labeled with the succinimidyl ester of 7-amino-4-methylcoumarin-3-acetic (AMCA). Although a large number of residues were labeled, it was found that Lys-492 was labeled preferentially at pH values between 6 and 8, consistent with an
