Product Data Sheet
Cy5-bifunctional dye potassium
Catalog No. A45517
Cy5-bifunctional dye potassium is a water-soluble fluorescent dye featuring two terminal NHS ester functionalities. This reagent enables selective and efficient reactions with primary amines, such as those found in lysine residues or aminosilane-coated surfaces, under neutral to slightly basic conditions, resulting in stable covalent bonds. Its bifunctional nature makes it suitable for cross-conjugation of amines and a variety of advanced labeling applications in chemical and biological research.
