Cyanine 7.5 maleimide chloride

Cy7.5 maleimide chloride is a type of CY dye, where CY stands for the cyanine class of compounds, consisting of 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 simple synthesis. CY dyes are frequently used to label proteins, antibodies, and small molecular compounds. For antibody labeling, the dyes can be conjugated through a straightforward mixing reaction, making them a useful reference for protein and antibody labeling methods.
