ATT 647N azide is a far-red fluorescent dye derivative functionalized with an azide group for copper-catalyzed or copper-free click chemistry (CuAAC or SPAAC) with alkyne-bearing biomolecules. The dye is based on the ATT 647N — a highly photostable, zwitterionic carbopyronine fluorophore with excellent brightness and low triplet formation. ATT 647N exhibits strong absorption in the red spectral range and high fluorescence quantum yield with emission maximum around 662 nm.
The azide functionality enables bioorthogonal conjugation to alkyne-modified nucleic acids, glycans, proteins, lipids, and other metabolic labels. ATT 647N azide provides stable fluorescent tagging compatible with fixed-cell imaging, flow cytometry, confocal, and high-resolution microscopy (SIM, STED, etc.). The dye’s neutral, hydrophilic structure minimizes nonspecific interactions and improves performance in aqueous biological systems.
