This product is prepared by labeling highly cross-adsorbed goat anti-chicken IgY (IgG) (H+L) with CF™660C. CF™660C is a cyanine-based dye engineered to be highly water-soluble without being excessively charged. As a result, CF™660C-antibody conjugates have high signal-to-noise ratio in immunostaining. CF™660C is several fold brighter and significantly more photostable than Alexa Fluor® 660. CF™660C absorbs at 667 nm but can still be sufficiently excited by the 633 or 635 nm laser with emission at 685 nm in the borderline spectral region between far-red and near-IR fluorescence. Please also see CF™660R, an exceptionally photostable 660 nm dye ideal for confocal microscopy. To minimize crossreactivity, the antibody has been adsorbed against bovine, goat, guinea pig, Syrian hamster, horse, human, mouse, rabbit, rat, and sheep serum.Compatible with the NucleoCounter® NC-3000™.
