Apexbio Technology LLC Cy3 NHS ester (non-sulfonated) 5mg
Cy3 NHS ester (non-sulfonated) is an amine-reactive fluorescent cyanine dye commonly utilized in labeling biomolecules via covalent conjugation to primary amines As a cyanine derivative its fluorescence emission occurs at approximately 570 nm upon excitation near 550 nm allowing detection in the orange spectral region using standard TRITC filter sets commonly integrated in fluorescence microscopy imaging systems and spectroscopic instruments The dye s labeling procedure requires organic solvents such as DMF or DMSO due to its limited aqueous solubility In biomedical research Cy3 NHS ester is routinely employed for labeling peptides proteins nucleic acids and oligonucleotides facilitating visualization and tracking in biomolecular assays cell imaging gel electrophoresis analyses and flow cytometry experiments
