General description

Immunoglobulin G (IgG) is the most crucial glycoprotein antibody. It has the longest serum half-life compared to other immunoglobulins. IgG is present in human serum and also identified in the bloodstream. It contains four polypeptide chains, wherein the light and heavy chains are linked by disulfide bonds.

Application

Human IgG, Fab Fragment, Plasma has been used in enzyme-linked immunosorbent assay (ELISA).

Biochem/physiol Actions

Immunoglobulin G (IgG) initiates the classical pathway of the complement system and eliminates virus particles and toxins. It controls antibody-dependent cell-mediated cytotoxicity (ADCC) and might be correlated to allergy. Digestion of IgG by papain generates fragment antigen-binding (Fab) whereas pepsin digestion of IgG releases crystallizable (Fc) fragment and a single dimeric F(ab)2.  Maternal IgG is transferred to the fetus via the placenta and is crucial for the immune defense of the neonate against infections. IgG levels in severe acute respiratory syndrome coronavirus (SARS-CoV)2 infected patients may be useful to understand the severity and prognosis of coronavirus disease 2019 (COVID-19).

Immunoglobulins are heterodimeric proteins composed of 2 heavy and 2 light chains. They can be separated functionally into variable domains that bind antigens and constant domains that specify effector functions, such as activation of complement or binding to Fc receptors.
