This product is prepared by labeling high quality rabbit anti-goat IgG (H+L) with our superior near-IR fluorescent dye CF680. 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.
