CF750 goat anti-mouse IgG is an affinity-purified goat anti-mouse IgG labeled with the near-IR fluorescent dye CF750, one of an outstanding series of CF dyes developed by Biotium. Our CF750-labeled antibodies are suitable for flow cytometry with 633 nm excitation. Although the absorption peak of the conjugate is at 755 nm, excitation at 633 or 635 nm still yields excellent fluorescence. In fact, our CF750 antibody conjugates are brighter and more specific than antibodies labeled with APC-Alexa Fluor? 750 tandem dye (See Near-IR CF flyer).
