Goat IgG Fraction to Mouse IgG (Whole Molecule), 2mL

The total protein is measured using the Biuret procedure, with bovine albumin as a standard. Antibody titer is standardized to an in-house standard by equivalence-point precipitation. Each IgG fraction is tested for purity and specificity at a minimum of 40 mg/mL using immunoelectrophoresis; No trace of albumin is detected. Antibody activity to non-immunoglobulin serum proteins is not present. The IgG fraction is prepared from the specific goat antiserum by delipidation, ammonium sulfate fractionation and anion exchange chromatography. The resulting IgG fraction is dialyzed into 0.02M sodium phosphate, 0.14M sodium chloride, pH 7.3, adjusted to standard titer, filtered through a 0.22 μm filter, vialed and lyophilized. IgG antibody subtype is the most abundant serum immunoglobulins of the immune system. It is secreted by B cells and is found in blood and extracellular fluids and provides protection from infections caused by bacteria, fungi and viruses. Maternal IgG is transferred to fetus through the placenta that is vital for immune defence of the neonate against infections. Anti-Mouse IgG (whole molecule) antibody recognizes IgG1, G2a, G2b, and G3, mouse IgM and IgA. The identity and purity of affinity isolated antibody is established by immunoelectrophoresis. Goat IgG fraction to mouse IgG (whole molecule) is used in immunostaining of acetone-fixed frozen and formalin-fixed, paraffin-embedded tissue sections. The antibody was used in ELISA and RIA in various studies. It is also suitable for use as a precipitating antibody. It gives sharp precipitin lines in immunoelectrophoresis and immunodiffusion techniques. This product is suitable for conjugation with enzymes, radiolabels, fluorochromes or other markers, and for attachment to solid supports for use as an immunoadsorbant. This product is suitable for use as a primary reagent in enzyme immunoassays, fluorescein immunoassays and blot, cell or tissue immunostaining. (Note: F(ab')₂ fragments are recommended for staining of cells or tissues which contain Fc receptors. Affinity purified antibodies are recommended to avoid non-specific binding from the inherent antibodies of host animals). Product is the lyophilized powder of goat IgG fraction to mouse IgG (whole molecule) and buffer salts. Reconstitution: Reconstitute product with 2.0 mL of deionized or distilled water. Gentle swirling may be used to speed rehydration. Avoid vigorous shaking of the reconstituted material.
