Sulfo-Cy5-Mal potassium 

Sulfo-Cy5-Mal potassium is a fluorescent dye derivative composed of a CY5 dye and a maleimide functional group. Sulfo-Cy5-Mal potassium specifically covalently binds to thiol-containing (-SH) biomolecules. Sulfo-Cy5-Mal potassium can be used for protein labeling, antibody conjugation, molecular imaging, and drug delivery studies (Ex/Em = 633 nm/670 nm)^[1].

Sulfo-Cy5-Mal potassium can covalently bind to thiol groups on antibodies, enzymes, or peptide molecules to achieve fluorescent labeling.
Sulfo-Cy5-Mal potassium can also be conjugated to nanoparticles, liposomes, or other biological carriers for tracking drug delivery, cellular uptake, and pharmacokinetic studies.
