This product is prepared by labeling highly cross-adsorbed rabbit anti-mouse IgG (H+L) with our near-IR fluorescent dye CF™680. The antibody has been adsorbed against human serum to minimize cross-reactivity. CF™680 is brighter than other spectrally similar dyes. Most importantly, antibody conjugates prepared from CF™680 have by far the best signal-to-noise ratio than antibody conjugates prepared from other spectrally similar dyes. Please also check out our CF™680R, an extremely photostable rhodamine-based near-IR dye. Please download the CF™680 dye flyer for more details.
