AFDye™ 647 Azide is a water-soluble, pH-insensitive from pH 4 to pH 10, far-red-fluorescent probe. Its excitation ideally suited for the 633 nm or 647 nm laser lines. AFDye™ 647 is structurally similar to Alexa Fluor® 647, and spectrally is almost identical to Cy5 Dye, Alexa Fluor® 647, CF® 647 Dye, or any other Cyanine5 based fluorescent dyes.

AFDye™ 647 Azide is a water-soluble, pH-insensitive from pH 4 to pH 10, far-red-fluorescent probe with excitation ideally suited for the 633 nm or 647 nm laser lines. A significant advantage to using long wavelength dyes such as Cy5 or AFDye™ 647 over other fluorophores is the low autofluorescence of biological specimens in this region of the spectrum.

AFDye™ 647 Azide can be reacted with terminal alkynes via a copper-catalyzed click reaction (CuAAC). It also reacts with strained cyclooctyne via a copper-free “click chemistry” reaction to form a stable triazole and does not require Cu-catalyst or elevated temperatures. The brightness and photostability of this dye are best suited to direct imaging of low-abundance targets.

AFDye™ 647 is structurally similar to Alexa Fluor® 647, and spectrally is almost identical to Cy5 Dye, Alexa Fluor® 647, CF® 647 Dye, or any other Cyanine5 based fluorescent dyes. AFDye™ 647 Azide can be used a less expensive alternative to Alexa Fluor® 647 Azide.
