Cyanine5.5 Maleimide is a near-infrared fluorescent probe and the maleimide derivative of Cyanine5.5. Its maleimide group covalently reacts with thiol (-SH) groups on proteins, antibodies, and other biomolecules to form stable thioether bonds. Emitting in the near-infrared window, this dye reduces biological autofluorescence and improves tissue imaging performance. Cyanine5.5 maleimide is widely used for in vivo small-animal imaging probe construction, protein labeling, and flow cytometry studies.
