This product is prepared by labeling highly cross-adsorbed donkey anti-goat IgG (H+L) with our near-IR fluorescent dye CF750. The antibody has been adsorbed against chicken, guinea pig, Syrian hamster, horse, human, mouse, rabbit, and rat serum to minimize crossreactivity. CF750 is brighter than other spectrally similar dyes. Most importantly, antibody conjugates prepared from CF750 have by far the best signal-to-noise ratio than antibody conjugates prepared from other spectrally similar dyes.
