On demandInvitrogen™ Alexa Fluor™ 647 C2 Maleimide
Alexa Fluor® 647 is a bright, far-red fluorescent dye with excitation ideally suited for the 594 nm or 633 nm laser lines. Used for stable signal generation in imaging and flow cytometry, Alexa Fluor® 647 dye is water soluble and pH-insensitive from pH 4 to pH 10. In addition to reactive dye formulations, we offer Alexa Fluor® 647 dye conjugated to a variety of antibodies, peptides, proteins, tracers, and amplification substrates optimized for cellular labeling and detection.
The maleimide derivative of Alexa Fluor® 647 is the most popular tool for conjugating the dye to a thiol group on a protein, oligonucleotide thiophosphate, or low molecular weight ligand. The resulting Alexa Fluor® 647 conjugates exhibit brighter fluorescence and greater photostability than the conjugates of other spectrally similar fluorophores.
