Biological Activity: Cy3-SE (Sulfo-Cy3 NHS ester; Sulfo Cyanine3 NHS ester) is a sulfonated cyanine dye-derived fluorescent labeling reagent with λex of about 515 nm and λem of about 568 nm. Cy3-SE can interact with the π-π stacking of biomolecules (e.g., nucleoside monophosphates, proteins), inhibiting the photoisomerization process and increasing the fluorescence quantum yield and lifetime[1][2].
