Cy3 Alkyne can be reacted with azides via a copper-catalyzed click reaction (CuAAC) forming a stable triazole and does not require elevated temperatures. This red fluorescent probe is water-soluble, and its fluorescence is pH-insensitive from pH 4 to pH 10. Its excitation peak is ideally suited for the 532 nm or 555 nm laser lines and its absorption and emission spectra are almost identical to those of Alexa Fluor® 555, CF® 555 Dye or any other Cyanine3 based fluorescent dyes.
