Produktbeschreibung

Produktmerkmale: Purified IgG fraction of polyclonal guinea pig antiserum to swine insulin

Weitere Bezeichnung: Insulin

Immunogen: Insulin is a hormone produced by the beta cells of the islets of Langerhans in the pancreas. It plays an important role in the metabolism of carbohydrate by its effects on the storage of glycogen in the liver, the conversion of carbohydrate to fat, and the oxidation of glucose by the peripheral tissues. Insulin has a molecular weight of 6,000 and contains two peptide chains linked by two disulphide bonds. The hormone is isolated from porcine pancreas. Freund’s complete adjuvant is used in the first step of the immunization procedure.

Beschreibung: The reactivity of the antiserum is directed to insulin as tested by ELISA and immunoblotting. No reaction was obtained with other swine serum proteins.

Spezifität: Inter-species cross-reactivity is a normal feature of antibodies to mammalian proteins, 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. Physicochemical characteristic IgG protein concentration 10 mg/ml. No foreign proteins added.

Anwendungen

Applikationshinweise: The cytochemical grade allows the 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 1:250, in ELISA and comparable non-precipitating antibody-binding assays are between 1:500 and 1:5,000. Adsorption: Immunoaffinity adsorbed using insolubilized antigens as required to eliminate antibodies cross-reacting with other serum proteins. The use of insolubilized adsorption antigens prevents the presence of excess adsorbent protein or immune complexes in the antiserum.

Reinigung: Hyperimmune antisera with strong precipitating activity are selected for fractionation by salt-precipitation and purification of the IgG (7S) fraction by DEAE-chromatography.

Buffer: Purified hyperimmune guinea pig IgG lyophilized from a solution in phosphate buffered saline (PBS, pH 7.2). Preservative: No preservative added, as it may interfere with the antibody activity.

Lagerung: Lyophilised at +4°C (10 years), reconstituted at or below -20°C (3-5 years), reconstituted at +4°C at least 7 days. The lyophilized product is shipped at ambient temperature and may be stored at +4°C, prolonged storage at or below -20°C. It is reconstituted by adding 1 ml sterile di stilled water, spun down to remove insoluble particles, divided into small aliquots, frozen and stored at or below -20°C. Prior to use, an aliquot is thawed slowly at ambient temperature, spun down again and used to prepare working dilutions by adding sterile phosphate buffered saline (PBS, pH 7.2). Repeated thawing and freezing should be avoided. Working dilutions should be stored at +4°C, not refrozen, and preferably used the same day. If a slight precipitation occurs upon storage, this should be removed by centrifugation. It will not affect the performance of the product.
