General description

IgG antibody subtype is the most abundant 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. Anti-Human IgG (γ-chain specific), F(ab′)2 fragment antibody is specific for human IgG subclasses. The F(ab′)2 fragment of the antibody is obtained from pepsin-digested antiserum by immunospecific methods of purification.

Immunogen

Purified human IgG

Application

Anti-Human IgG (γ-chain specific), F(ab′)2 fragment antibody is suitable for Ouchterlony double diffusion and quantitative precipitin assay. The antibody was used in ELISA and to produce Fab′-oligonucleotide conjugates.

Physical form
