Immunoglobulin G information


The water-accessible surface area of an IgG antibody

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.[1] IgG molecules are created and released by plasma B cells. Each IgG antibody has two paratopes.
