一般描述
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.
特异性
The antiserum is determined to be immunospecific for human IgG, IgA and IgM. Reactivity is also observed against light chains.
应用
Anti-Human Polyvalent Immunoglobulins (G,A,M) antibody produced in goat has been used in immunoassays/sandwich immunoassay and enzyme-linked immunosorbent assay (ELISA).
生化/生理作用
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.
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.
外形
The antibody is supplied as a liquid containing 0.1% sodium azide.
储存及稳定性
For continuous use, store at 2-8 ℃ for up to one month. For extended storage, the solution may be frozen in working aliquots. Repeated freezing and thawing is not recommended. Storage in "frost-free" freezers not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use.
