sulfo-Cyanine3 azide is a water-soluble dye azide for click chemistry. Absorbance and emission of the dye are identical to Cy3® fluorophore.

Brightness and photostability of the fluorophore, together with high water solubility, make this reagent an ideal choice for click chemistry labeling various molecules in the aqueous phase.

Click reaction can be carried out in pure water without the need to use organic co-solvent. The reagent is designed for the labeling of sensitive molecules and even intact biological objects.
