Cyanine3 DBCO hexafluorophosphate（Cat No.:I043060）is a fluorescent dye conjugate that combines the Cyanine3 fluorophore, known for its high brightness and near-infrared emission, with a dibenzocyclooctyne (DBCO) group. The DBCO group enables efficient, bioorthogonal conjugation to azide-functionalized biomolecules via click chemistry, making it ideal for labeling proteins, nucleic acids, and other molecules in biological systems. This compound is widely used in fluorescence microscopy, flow cytometry, and live-cell imaging to study molecular interactions, cell tracking, and cellular processes. The hexafluorophosphate counterion helps enhance the dye’s solubility and stability in aqueous solutions.
