Description_x000D_ General description_x000D_ Human IgGs are glycoprotein antibodies that contain two equivalent light chains and a pair of identical heavy chains. IgGs have four distinct isoforms, ranging from IgG1 to IgG4. These antibodies regulate immunological responses to allergy and pathogenic infections. IgGs have also been implicated in complement fixation and autoimmune disorders . Anti-human IgG (whole molecule) antibody is specific for human IgG when tested against normal human serum and IgG by immunoelectrophoresis. The antibody also reacts with light chains. Immunoglobulin G (IgG) is part of the immunoglobulin family and is a widely expressed serum antibody. It consists of a γ heavy chain in the constant (C) region. The primary structure of this antibody contains disulfide bonds involved in linking the two heavy chains, linking the heavy and light chains and also resides inside the chains._x000D_ Immunogen_x000D_ Human IgG_x000D_ Application_x000D_ Anti-Human IgG (whole molecule) antibody is suitable for use in quantitative precipitin assay (3.0 mg/mL)._x000D_ Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below._x000D_ Western Blotting (1 paper)_x000D_ Physical form_x000D_ Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide as preservative_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.
