ATT 633 is a far-red fluorescent dye with high fluorescence quantum yield, strong thermal and photostability, and excellent water solubility. The dye is well-suited for high-resolution microscopy and single-molecule detection applications.
ATT 633 is a cationic dye. After coupling to a substrate, the dye carries a net electrical charge of +1.
ATT 633 azide is a fluorescently labeled azide that reacts with alkynyl derivatives of biomolecules (terminal alkynes and cyclooctynes) via click reactions to form stable adducts.

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.Cyanine5 carboxylic acid
