Alexa Fluor® 594 Rabbit Anti-Goat IgG (H+L) is labeled with our bright, red-fluorescent Alexa Fluor 594 dye, which is spectrally similar to Texas Red dye. It is prepared from affinity-purified antibodies that react with IgG heavy chains and all classes of immunoglobulin light chains from goat. To minimize cross-reactivity, it has been adsorbed against human and rat serum proteins prior to labeling.
