Coumarin 343 in Fluorophores

Absorption max 437 nm Emission max 477 nm Fluorophore chart

Coumarin 343 X azide

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