Unconjugated Rabbit Anti-Goat IgG antibodies are purified by an affinity chromatography procedure to remove any low affinity antibodies, then cross-reactive antibodies are removed by solid-phase adsorption. The final product is subjected to rigorous quality control assays including immunodiffusion, solid-phase enzyme immunoassays, gel electrophoresis and solid-phase binding assays. These antibodies will recognize both heavy and light chains. Rabbit Anti-Goat IgG Antibody is supplied in solution and is ready for iodination, fluorochrome labeling, or enzyme conjugations. It can also be employed as a capture antibody in enzyme immunoassays or in other assays requiring carrier-free immunoglobulins. Blocking with Animal-Free Blocker™ solution (Cat. No. SP-5030; NC9592609) instead of bovine products (casein, albumin, milk) is recommended.
