Product Code Product Name Goat anti Human IgG IgA IgM (heavy and light chains) Size 10 mg Price (USD) $180 Background The reactivity of the antiserum is directed to the major isotypes of the human immunoglobulin system (classes and both light chain types) including antibodies to common determinants, to class and to the surface determinants of the common Fab portion, as tested by immunoelectrophoresis and double radial immunodiffusion against pooled serum and purified immunoglobulins. In immunoelectrophoresis and double radial immunodiffusion using various antiserum concentrations against normal human plasma and serum, the characteristic IgG, IgA and IgM precipitin lines are obtained. The cytochemical grade of GAHu/Ig/7S allows its use in different types of highly sensitive immunoassays on appropriately treated cell and tissue substrates; in radioimmunoassay; for the production of immunoconjugates with a selected marker; to prepare immunoaffinity adsorbents by coupling to an artificial carrier; in non-isotopic methodology based on solid phase immunochemistry (e.g. ELISA), both as catching antibody and detection reagent; in Western blotting. This product is not pre-diluted. The optimum working dilution of each product should be established by titration before being used. Working dilutions for histochemical and cytochemical use are usually between 1:100 and 1:500; in ELISA and comparable non-precipitating antibody-binding assays are between 1:1,000 and 1:5,000. Host Goat Species Reactivity Human Product Usage Purified IgG fraction of polyclonal Goat antiSerum to Human immunoglobulins IgG, IgA, IgM, heavy and light chains Product Type Secondary Antibodies Applications Immunoprecipitation Fields of Interest Immunology Product Source Highly purified IgG and pools of homogenous IgA and IgM isolated from human serum. Freund Product Formulation Purified hyperimmune goat IgG lyophilized from a solution in phosphate buffered saline (PBS, pH 7.2). No preservative added, as it may interfere with the antibody activity. Product Specificity Inter-species cross-reactivity is a normal feature of antibodies to mammalian immunoglobulins, since homologous proteins of different species frequently share antigenic determinants. The degree of cross-reactivity is also dependent on the concentRations of the reactants and the sensitivity of the assay arrangement. This antiSerum fraction has not been tested for cross-reactivity. Storage Conditions The lyophilized product is shipped at ambient temperature and may be stored at +4
