Home Products Dye Labeling Cyanine Labeling Cyanine-PEG-Maleimide

Cyanine-PEG-Maleimide is a cyanine labeled PEG derivative containing a maleimide group, which can selectively and efficiently react with thiols to form a covalent bond, enabling the connection of thiol-bearing biomolecules. Hydophilic PEG spacer increases solubility in aqueous media and membrane impermeability.
