This product is prepared by labeling highly cross-adsorbed donkey anti-guinea pig IgG (H+L) with our superior far-red fluorescent dye CF633. CF633 is brighter than Alexa Fluor® 647 and other spectrally similar dyes on antibodies. But most importantly, CF633 has unmatched photostability, making it the best choice for demanding applications, such as confocal microscopy and single molecule imaging. Please download the CF633 dye flyer for more details. To minimize cross-reactivity, the antibody has been adsorbed against bovine, chicken, goat, Syrian hamster, horse, human, mouse, rabbit, sheep and rat serum.Compatible with the NucleoCounter® NC-3000™.
