General description

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.

Specificity

The antibody preparation is specific for human IgG when tested against purified human IgA, IgG, IgM, Bence Jones kappa and Bence Jones lambda myeloma proteins.

Biochem/physiol Actions

IgG antibody subtype is the most abundant serum immunoglobulin 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.
Immunoglobulin G (IgG) mainly participates in hypersensitivity type II and type III.

Physical form

Supplied as a liquid containing 15mM sodium azide as a preservative.

Preparation Note

delipidized

Storage and Stability

For continuous use, store at 2-8 °C 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.
