APDye Fluor 647 DBCO 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 APDye™ Fluor 647 dye over other fluorophores is the low autofluorescence of biological specimens in this region of the spectrum.
APDye™ Fluor 647 DBCO is a bright, far-red fluorescent, probe routinely used for imaging of azide-containing biomolecules without the need for copper catalyst. APDye™ Fluor 647 DBCO reacts with azides via a copper-free “click chemistry” reaction to form a stable triazole and does not require Cu-catalyst or elevated temperatures. In application where the presence of copper is a concern APDye™ Fluor 647 DBCO is an ideal alternative to copper requiring fluorescent alkynes.
APDye™ Fluor 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.
