Home Products Dye Labeling Cyanine Labeling Cyanine-PEG-DBCO

Cyanine-PEG-DBCO is a cyanine labeled PEG derivative containinig DBCO group, which reacts with azide functionalized compounds or biomolecules to form a stable triazole linkage without copper catalyst. DBCO-activated fluorescein dye will be an ideal alternative to copper intolerant applications and the hydophilic PEG spacer arm increases solubility in aqueous media and membrane impermeability.
