Alexa Fluor® 594 Goat Anti-Rat IgG (H+L) is labeled with our superior red-fluorescent Alexa Fluor 594 dye. It is prepared from affinity-purified antibodies that react with IgG heavy chains and all classes of immunoglobulin light chains from rat. To minimize cross-reactivity, it has been adsorbed against mouse IgG, mouse serum and human serum prior to conjugation.
