Alexa Fluor® 532 Goat Anti-Mouse IgG (H+L) is labeled with our exceptionally bright, yellow-fluorescent Alexa Fluor 532 dye. It 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 human IgG and human serum prior to conjugation.
