AFDye™ 546 DBCO an azide reactive probe that can be used for imaging azide-tagged biomolecules via a copper-free “click reaction”. DBCO moiety reacts with azides to form a stable triazole and does not require Cu-catalyst or elevated temperatures. In application where the presence of copper is a concern AFDye™ 546 DBCO is an ideal alternative to copper requiring fluorescent alkynes.

AFDye™ 546 is water-soluble, and pH-insensitive from pH 4 to pH 10 orange-fluorescent dye with absorption and emission maxima at 554 and 570 nm, respectively. It can be used with the 488 nm and 532 nm laser lines. AFDye™ 546 dye conjugated to a variety of antibodies, peptides, proteins, tracers, and amplification substrates often used for generation of stable signal in imaging and flow cytometry.

AFDye™ 546 dye structurally is identical to Alexa Fluor® 546 dye sold by ThermoFisher Scientific.
