BP Fluor 647 Azide

BP Fluor 647 Azide (Alexa Fluor® Azide analog) is a water-soluble, pH-insensitive from pH 4 to pH 10 bright, 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 BP Fluor 647 dye over other fluorophores is the low autofluorescence of biological specimens in this region of the spectrum. The brightness and photostability of this dye are best suited to direct imaging of low-abundance targets.
