Background
|
Immunoglobulin G (IgG) are antibody molecules. Each IgG is composed of four peptide chains - two heavy chains gamma and two light chains. Each IgG has two antigen s. Other Immunoglobulins may be described in terms of polymers with the IgG structure considered the monomer. IgG constitutes 75 % of serum immunoglobulins in humans. IgG molecules are synthesized and secreted by plasma B cells.
Synonyms: Rodent IgG isotype control.
