Description_x000D_ General description_x000D_ Immunoglobulin G (IgG) belongs to the immunoglobulin family and is a widely expressed serum antibody. It consists of a γ heavy chain in the constant (C) region. The monomeric 150kDa structure of IgG constitutes two identical heavy chains and two identical light chains with molecular weight of 50kDa and 25kDa respectively. The primary structure of this antibody also contains disulfide bonds involved in linking the two heavy chains, linking the heavy and light chains and resides inside the chains. IgG is further subdivided into four classes namely, IgG1, IgG2, IgG3, and IgG4 with different heavy chains, named γ1, γ2, γ3, and γ4, respectively. Limited digestion using papain cleaves the antibody into three fragments, two of which are identical and contain the antigen-binding activity. They are known as fragment antigen binding (Fab) fragments. These fragments contain the light chains paired with the VH and CH1 domains of the heavy chains. Pepsin cleaves the carboxy-terminal side of the disulfide bonds in the general region of the antibody and this gives rise to the F(ab’)2 fragment. The two antigen-binding arms of the antibody are linked in this fragment. Maternal IgG is the only antibody transported across the placenta to the fetus. It passively immunizes the infants._x000D_ Specificity_x000D_ This product was prepared from monospecific antiserum by immunoaffinity chromatography using Mouse IgG coupled to agarose beads followed by solid phase adsorption(s) to remove any unwanted reactivities. Assay by immunoelectrophoresis resulted in a single precipitin arc against Anti-Goat Serum, Mouse IgG, Mouse IgG F(ab’)2 and Mouse Serum. No reaction was observed against Mouse IgG F(c)._x000D_ Immunogen_x000D_ Mouse IgG F(ab′)2 fragment_x000D_ Physical form_x000D_ Supplied in 0.02 M Potassium Phosphate, 0.15 M Sodium Chloride, pH 7.2 with 10 mg/mL Bovine Serum Albumin (BSA) - Immunoglobulin and Protease free_x000D_ Reconstitution_x000D_ Reconstitute with 1.0 mL deionized water (or equivalent)._x000D_ Disclaimer_x000D_ Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals._x000D_ Physical properties_x000D_ Antibody format: IgG
