This highly cross-adsorbed Oregon Green 488 goat anti—rabbit IgG is labeled with our proprietary, bright, green-fluorescent 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.
