This product is prepared by labeling highly cross-adsorbed donkey anti-guinea pig IgG (H+L) with CF™405S. CF™405S is a blue fluorescent dye with an absorption peak wavelength that nearly coincides with the 405 nm blue diode laser line. In addition, the emission peak wavelength of the dye well centers within the blue detection window of BD flow cytometers. As a result, flow cytometry analysis using CF™405S dye results in much brighter signal than that using Alexa Fluor® 405. To minimize cross reactivity, the antibody has been adsorbed against Bovine, Chicken, Goat, Syrian Hamster, Horse, Human, Mouse, Rabbit, and Sheep serum.Compatible with the NucleoCounter® NC-3000™.
