Cyanine 3.5 maleimide chloride

Cyanine3.5 maleimide chloride is a type of CY dye, where CY stands for cyanine, a compound with two nitrogen atoms linked by an odd number of methine units. Cyanine compounds are known for their long wavelengths, adjustable absorption and emission, high extinction coefficients, good water solubility, and relatively straightforward synthesis. CY series dyes are frequently used for labeling proteins, antibodies, and small molecules. Protein and antibody labeling can be achieved through a simple mixing reaction. Below, we outline a method for labeling proteins and antibodies, which may serve as a useful reference.
