BP Fluor 633 Azide is a far-red fluorescent cationic dye with high fluorescence quantum yield, strong thermal and photostability, and excellent water solubility. BP Fluor 633 Azide is comparable to Alexa Fluor 633 Azide. The dye is well-suited for high-resolution microscopy and single-molecule detection applications. After coupling to a substrate, the dye carries a net electrical charge of +1. BP Fluor 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.
