ROX azide is an alkyne-reactive derivative of ROX (Rhodamine X, Rhodamine 101) dye. ROX is a red-emitting fluorophore possessing high brightness and fluorescence quantum yield. This reagent is a pure 5-isomer. It is used for labeling alkyne and cycloalkyne-containing biomolecules via copper-catalyzed and copper-free click chemistry reactions.

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.

VIC azide, 6-isomer

VIC is an asymmetric xanthene dye with spectral properties similar to HEX and JOE, widely used for labeling PCR probes. This derivative is an azide for dye conjugation by click chemistry.
