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.

AMCA carboxylic acid

Non-reactive form of AMCA fluorescent dye with a free carboxyl group. AMCA is one of the brightest blue fluorescent dyes with large Stoke's shift and high resistance to photobleaching.
