Human IgGs are glycoprotein antibodies that contain two equivalent light chains and a pair of identical heavy chains. IgGs have four distinct isoforms, ranging from IgG1 to IgG4. These antibodies regulate immunological responses to allergy and pathogenic infections. IgGs have also been implicated in complement fixation and autoimmune disorders. Goat Anti-Human IgG (γ-chain specific)-Peroxidase antibody is specific for human IgG when tested against human IgA, IgG, IgM, Bence Jones Kappa and Lambda myeloma proteins.
