This product is prepared by labeling highly cross-adsorbed goat anti-mouse IgG (H+L) with CF568. CF568 is a red fluorescent dye with an excitation spectrum optimally matching the 568 nm line of the Ar-Kr mixed-gas laser. Antibody conjugates of the dye are much brighter than those of Alexa Fluor? 568. In addition, the photostability of CF568 is superior to that of Alexa Fluor? 568, making CF568 a much better choice for demanding applications, such as confocal microscopy and single molecule imaging. To minimize cross-reactivity, the antibody has been adsorbed against human, bovine, horse, rabbit, and swine serum.
