Alexa Fluor® 594 Goat Anti-Human IgG (H+L) is labeled with our superior 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 human. To minimize cross-reactivity, it has been adsorbed against mouse, rabbit and bovine serum prior to conjugation.
