This highly cross-adsorbed Alexa Fluor® 546 Goat Anti-Rabbit IgG (H+L) is labeled with our bright, photostable, orange-fluorescent Alexa Fluor 546 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 cross-reactivity, it has been adsorbed against bovine IgG, goat IgG, mouse IgG, rat IgG and human IgG.
