Alexa FluorŪ 546 Goat Anti-Rabbit IgG (H+L) is labeled with our bright, photostable, orange-fluorescent Alexa Fluor 546 dye. It 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 humanIgG, human serum, mouseIgG, mouse serum and bovine serum. We also provide a version of the same antibody that has been cross-adsorbed against additional species (A-11035).
