CY5 triethylamine

CY5 triethylamine is a type of CY dye, where CY stands for cyanine, a compound consisting of two nitrogen atoms connected by an odd number of methine units. Cyanine compounds are characterized by their long wavelengths, adjustable absorption and emission, high extinction coefficients, good water solubility, and relatively simple synthesis. CY dyes are commonly used for labeling proteins, antibodies, and small molecules. The labeling of proteins and antibodies can be achieved through simple mixing reactions, and we provide a method for labeling protein antibodies, which serves as a practical reference.
