This product is prepared by labeling highly cross-adsorbed donkey anti-goat IgG (H+L) with our near-IR fluorescent dye CF680. The antibody has been adsorbed against chicken, guinea pig, Syrian hamster, horse, human, mouse, rabbit, and rat serum to minimize cross-reactivity. CF680 is brighter than other spectrally similar dyes. Most importantly, antibody conjugates prepared from CF680 have by far the best signal-to-noise ratio than antibody conjugates prepared from other spectrally similar dyes. Please also check out our CF680R, an extremely photostable rhodamine-based near-IR dye. Please download the CF680 dye flyer for more details.
