Trisulfo-Cy3 amine disodium

Cy3B amine chloride is a derivative of Cyanine 3 (Cy3) dye in a disodium salt form, featuring an amine group. Cy3 is a fluorescent dye with emission typically in the green to orange wavelength range. The amine functional group of Sulfo-Cy3 amine can react with carboxyl groups to form covalent bonds. Sulfo-Cy3 amine can bind to biomolecules like proteins and antibodies, allowing the tracking of their location and dynamic changes in biological samples.
