    Immunoglobulin G - Wikipedia

    • Immunoglobulin G (IgG) is a type of antibody. Representing approximately 75% of serum antibodies in humans, IgG is the most common type of antibody found in blood circulation. IgG molecules are created and released by plasma B cells. Each IgG antibody has two paratopes. 展开

    Structure

    IgG antibodies are large globular proteins made of four peptide chains; two identical γ (gamma) heavy chains of about 50 kDa and two identical light chains of about 25 kDa. The resulting tetrameric quaternary structure, therefo… 展开

    Subclasses

    There are four IgG subclasses (IgG1, 2, 3, and 4) in humans, named in order of their abundance in serum (IgG1 being the most abundant).

    Role in diagnosis

    The measurement of immunoglobulin G can be a diagnostic tool for certain conditions, such as autoimmune hepatitis, if indicated by certain symptoms. Clinically, measured IgG antibody levels are generally considered to b… 展开
