IgG (immunoglobulin G) consists of four subclasses: IgG1, IgG2, IgG3 and IgG4. The IgG structure possesses four polypeptide chains containing two identical γ heavy (H) chains and two identical κ or λ light (L) chains of 50kDa and 25kDa respectively. The chains are interlinked with a disulfide bond. Both the L and the H chains consist of a variable domain at the N-terminal. The C-terminal bears′ constant domains: three in H chain with a hinge region and one in the L chain. IgG antibody is enriched in mother′s milk. IgG contributes to 10−20% of plasma protein and is regarded as one of the most abundant serum protein.
특이성
This product was prepared from monospecific antiserum by immunoaffinity chromatography using Rat 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-Rabbit Serum, Rat IgG and Rat Serum. No reaction was observed against Human Serum Proteins.

생화학적/생리학적 작용
IgG (immunoglobulin G) antibody protects against bacterial, fungal and viral infections. IgG antibody has its function similar to IgM antibody in complement system activation. IgG participates in hypersensitivity type II and type III. It helps in opsonization, complement fixation and antibody-dependent cell-mediated cytotoxicity. Maternal IgG is transferred to fetus through the placenta that is vital for immune defense of the neonate against infections.
