Home Products Dye Labeling Cyanine Labeling Cyanine-PEG-NHS ester

Cyanine-PEG-NHS ester is a cyanine labeled PEG derivative containing a NHS ester group, which is an amine reactive group. Hydophilic PEG spacer increases solubility in aqueous media and membrane impermeability. This reagent can be utilized to produce Cyanine-labeled biomolecules for subsequent use such as in vivo research, and drug design related experiments.
