This product is prepared by labeling highly cross-adsorbed donkey anti-goat IgG (H+L) with our near-IR fluorescent dye CF™680R. The antibody has been adsorbed against chicken, guinea pig, Syrian hamster, horse, human, mouse, rabbit, and rat serum to minimize cross-reactivity. CF™680R is a bright and exceptionally photostable near-IR dye. Although CF™680R is not as bright as our CF™680, it is still among the brightest 680 nm dyes. However, the most important feature of CF™680R is its unrivaled photostability. This makes CF™680R ideal for applications that demand both brightness and photostability. Please download the CF™680R dye flyer for more details.
