Thermo Scientific™ Hydrazide-AMCA (hydrazide-activated aminomethylcoumarin acetate)
AMCA (aminomethylcoumarin acetate) is a blue fluorescent dye with reactive derivatives that are used as contrasting probes for double- and triple-labeling in immunofluorescence microscopy, arrays and in situ hybridization. The desirable properties of AMCA dyes include a relatively large Stoke's shift and resistance to photobleaching. NHS-AMCA and Sulfo-NHS-AMCA are reactive towards primary amine groups on proteins, peptides and other biomolecules. AMCA-Hydrazide is used to label glycosylation sites or for conjugation to carboxyl groups using the crosslinker EDC. AMCA has an excitation maximum at 345nm and an emission maximum at 450nm.
Features
- AMCA —activated derivatives of blue-fluorescent aminomethylcoumarin acetate dye
- Amine-specific labeling—NHS-ester and Sulfo-NHS-ester varieties of AMCA efficiently label antibodies and other purified proteins at primary amines (lysine side chains)
- Glycoprotein labeling—hydrazide variety of AMCA labels oxidized sugar groups in glycoproteins or other carbohydrates
