CY7-SE triethylamine（Cat No.:I045875）is an amine-reactive near-infrared fluorescent dye belonging to the cyanine family, widely used for biomolecule labeling. The SE (succinimidyl ester) group allows efficient covalent conjugation to primary amines in proteins, peptides, and antibodies, enabling stable fluorescent tagging. With excitation and emission in the NIR range, CY7-SE provides low background autofluorescence and deep tissue penetration, making it highly suitable for in vivo imaging, flow cytometry, and fluorescence-based assays. The triethylamine form improves solubility and stability, ensuring reliable performance in bioimaging and molecular diagnostic applications.
