This product is prepared by labeling highly cross-adsorbed goat anti-rat IgG (H+L) with our superior near-IR fluorescent dye CF680. The antibody has been adsorbed against human, bovine, horse, and rabbit 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.
