This product is prepared by labeling highly cross-adsorbed donkey anti-mouse IgG (H+L) with CF™350. CF™350 is a blue fluorescent dye spectrally similar to the traditional blue fluorescent dye, AMCA. However, compared to AMCA, CF™350 is more water-soluble, more photostable and at least 50% more fluorescent on proteins. CF™350 is at least as bright as Alexa Fluor® 350 and thus can be a direct replacement for the latter for all applications. To minimize cross-reactivity, the antibody has been adsorbed against bovine, chicken, goat, guinea pig, Syrian hamster, horse, human, rabbit, and sheep serum.Compatible with the NucleoCounter® NC-3000™.
