Immunoglobulin G (IgG) belongs to the immunoglobulin family and is a widely expressed serum antibody. Immunoglobulin have two heavy chains and two light chains connected by a disulfide bond. It is a glycoprotein, usually found as a monomer. IgG is further subdivided into four classes namely, IgG1, IgG2, IgG3, and IgG4. IgG antibody subtype is the most abundant of serum immunoglobulins of the immune system. About 70 % of the total immunoglobulin consists of IgG.
The antiserum is determined to be immunospecific for human IgG. Reactivity with light chains is observed.
Anti-Human IgG (whole molecule) antibody produced in rabbit has been used in immunoprecipitation and enzyme linked immuno sorbent assay (ELISA).
Immunoglobulin G (IgG) participates in hypersensitivity type II and type III.
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 defense of the neonate against infections.

Storage and Stability
For continuous use, store at 2-8 °C. For extended storage, the solution may be frozen in working aliquots. Repeated freezing and thawing, or storage in "frost-free" freezers, is notrecommended.If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use.
