Sulfo-Cyanine 3 maleimide is a water soluble, thiol reactive dye for the labeling with hydrophilic sulfo-Cyanine 3 fluorophore. This is an analog of Cy3 maleimide. This product is recommended for the labeling of antibodies and other labile proteins in mild, purely aqueous conditions. The dye is water soluble and does not require use of organic co-solvent. A non-sulfonated Cyanine 3 maleimide is available.
