Sulfo-Cyanine7 azide
Water-soluble NIR fluorescent dye azide for Click chemistryCoumarin 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.General properties
