General description

Immunoglobulin G (IgG) belongs to the immunoglobulin family and is a widely expressed serum antibody. Immunoglobulins have two heavy chains and two light chains connected by a disulfide bond. It is a glycoprotein. IgG is usually found as a monomer. IgG is further subdivided into four classes namely, IgG1, IgG2, IgG3, and IgG4. About 70 percent of the total immunoglobulin consists of IgG.

Specificity

Reactivity is observed versus purified human IgA, IgM, Bence Jones Kappa and Bence Jones Lambda myeloma proteins. No reactivity is observed versus Fc fragment of human IgG.

Application

Anti-Human IgG (Fab specific) antibody produced in goat has been used in immunological assays. It has also been used in cellulose substrates as immobilized anti-hIgG to detect human immunoglobulin G (hIgG) from fluid matrices.
Anti-Human IgG (Fab specific) antibody produced in goat was used in capture ELISA at a dilution of 1:10,000.

Biochem/physiol Actions

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.

Physical form

Supplied as a liquid containing 15 mM 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.
