Cy5 maleimide is a thiol-reactive Cyanine5 fluorescent dye that selectively labels cysteine residues via a stable thioether linkage. It produces bright, long-wavelength fluorescence suitable for fluorescence imaging and detection, and is supplied as a high-purity reagent for research applications.

• Thiol-reactive maleimide group for selective cysteine conjugation.
• Bright, long-wavelength fluorescence ideal for imaging (approx. 648/671 nm).
• Forms a stable thioether linkage for durable labeling.
• High purity suitable for sensitive assays (≈99.4%).
• Soluble in common organic solvents such as DMSO and DMF.
• Store sealed, protected from moisture and light at -20°C.
