This product is prepared by labeling highly cross-adsorbed donkey anti-rabbit IgG (H+L) with CF®790 dye. CF® dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. Near-infrared fluorescent CF®790 dye has excitation/emission at 784/806 nm. To minimize cross-reactivity, the antibody has been adsorbed against bovine, chicken, goat, guinea pig, Syrian hamster, horse, human, mouse, rat, and sheep serum.
