Cy3 NHS ester is a CY dye, which stands for Cyanine. Cyanine compounds are characterized by having two nitrogen atoms connected by an odd number of methyl units. These dyes are known for their long wavelength, adjustable absorption and emission, high extinction coefficient, good water solubility, and relatively simple synthesis. CY dyes are frequently used for labeling proteins, antibodies, and small molecular compounds. Labeling protein antibodies can be achieved through a straightforward mixing reaction.

Cy3 NHS ester is a cyanine-based fluorescent labeling reagent that reacts with primary amines to covalently label proteins, peptides, antibodies, and small molecules for fluorescence imaging and detection. Supplied as a solid with high purity and good DMSO solubility, it is designed for reliable bioconjugation workflows and fluorescence-based assays.
- Reactive NHS ester for efficient amine coupling.
- Strong fluorescence with excitation ≈550 nm and emission ≈570 nm.
- High purity suitable for sensitive bioconjugation.
- Soluble in DMSO (about 125 mg/mL) for easy stock preparation.
- Stable when stored protected from light at -20°C; in solution, store at -80°C for long-term.
