This product is prepared by labeling highly cross-adsorbed goat anti-rabbit IgG (H+L) with our superior near-IR fluorescent dye CF680R. The antibody has been adsorbed against human, mouse, and rat serum to minimize cross-reactivity. CF680R is a bright and exceptionally photostable near-IR dye. Although CF680R is not as bright as CF680, it is still among the brightest 680 nm dyes. However, the most important feature of CF680R is its unrivaled photostability. This makes CF680R ideal for applications that demand both brightness and photostability. Please download the CF680R dye flyer for more details.
