一般說明
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.
應用
Human IgG, Fab Fragment, Plasma has been used in enzyme-linked immunosorbent assay (ELISA).
生化／生理作用
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.

Of the five immunoglobulin isotypes, immunoglobulin G (IgG) is most abundant in human serum. The four subclasses, IgG1, IgG2, IgG3, and IgG4, which are highly conserved, differ in their constant region, particularly in their hinges and upper CH2 domains. These
