This highly cross-adsorbed Alexa Fluor® 488 Goat Anti-Mouse IgG (H+L) is labeled with our bright, photostable, green-fluorescent Alexa Fluor 488 dye and is prepared from affinity-purified antibodies that react with IgG heavy chains and all classes of immunoglobulin light chains from mouse. To minimize cross-reactivity, it has been adsorbed against bovine IgG, goat IgG, rabbit IgG, rat IgG, human IgG and human serum.
