This highly cross-adsorbed Alexa Fluor 350 goat anti—rabbit IgG is labeled with our intense, blue-fluorescent Alexa Fluor 350 dye and is prepared from affinity-purified antibodies that react with IgG heavy chains and all classes of immunoglobulin light chains from rabbit. To minimize crossreactivity, it has been adsorbed against bovine IgG, goat IgG, mouse IgG, rat IgG and human IgG.
