AMCA (aminomethylcoumarin acetate) is one of the brightest blue fluorescent dyes. This fluorophore has a relatively large Stoke’s shift, high resistance to photobleaching, and pH-independent fluorescence from pH 4 to 10. AMCA is a widely used fluorophore for multiple-color labeling due to its minimal fluorescence overlap with green- and longer wavelength-emitting fluorescent dyes.
AMCA carboxylic acid is a non-reactive form of AMCA dye that can be used as a reference standard in experiments involving AMCA dye conjugates. Besides, the carboxylic group can react with hydrazines, hydroxylamines, and amines using carbodiimides such as EDAC.

AF 343 (Coumarin) X azide
AF 343 (Coumarin) is a blue emitting fluorophore that can serve as a FRET donor for fluorescein (FAM). This azide derivative can be conjugated with alkynes by сlick chemistry. An extended linker arm between the fluorophore and the azide group enhances solubility and provides spatial separation between the dye and the biomolecule.AF 532 carboxylic acid
