Description_x000D_ General description_x000D_ Anti-Human Polyvalent Immunoglobulins (G,A,M) is produced in goat using IgG and IgM isolated from normal human serum and human IgA from pooled human colostrum as the immunogens. Immunoglobulin G (IgG) belongs to the immunoglobulin family and is a widely expressed serum antibody. IgG is usually found as a monomer. IgG antibody subtype is the most abundant of serum immunoglobulins of the immune system. About 70 percent of the total immunoglobulin consists of IgG. Immunoglobulin M (IgM ) is a high molecular weight protein that has five or six subunits. Human serum shows low concentration of IgM monomers. It has a high carbohydrate content of about 12%. It is the first immunoglobulin produced by neonates._x000D_ Application_x000D_ Anti-Human Polyvalent Immunoglobulins (G,A,M) antibody produced in goat has been used in immunoassays/sandwich immunoassay and enzyme-linked immunosorbent assay (ELISA)._x000D_ Anti-Human Polyvalent Immunoglobulins (G,A,M) antibody produced in goat was used in sandwich immunoassays to test portable, disposable microfluidic devices._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_ Biochem/physiol Actions_x000D_ IgG antibody subtype is the most abundant of 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. IgA antibody is secretory antibody and is present abundantly in mucous linings of gastrointestinal, respiratory and genitourinary tracts, tears and saliva. IgM antibodies are present as pentamers in the serum and are produced in response to antigens._x000D_ Immunoglobulin G (IgG) participates in hypersensitivity type II and type III. Immunoglobulin M (IgM) acts as an antigen specific part of the B cell antigen receptor on the surface of B lymphocytes that are not stimulated, in its monomeric form. Polymeric IgM molecules also serve as important activators of the classical complement cascade. IgM is essential in agglutination and cytolytic reactions.
