BP Fluor 647 Amine

BP Fluor 647 (Alexa Fluor 647 analog) is a water-soluble, bright, far-red-fluorescent dye 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. It also can be employed as a polar tracer, a reactive dye for labeling proteins via a carboxylic acid moiety, and amine donor for enzymatic transamination labeling.
