APDye Fluor 647 Picolyl Azide
This product is a bright, far-red fluorescent probe containing a sulfonated 647 dye and a picolyl azide group. The dye provides intense, photostable emission around 665 nm, while the picolyl azide supports copper-catalyzed click chemistry (CuAAC) with enhanced reactivity compared to standard azides. Its water-soluble design makes it especially ideal for biomolecule labeling, imaging, and bioorthogonal conjugation.
