Immunoglobulin G (IgG) is a monomeric immunoglobulin, built of two heavy chains γ and two light chains - HERPES
Immunoglobulin G (IgG) is a monomeric immunoglobulin, built of two heavy chains γ and two light chains. Each IgG has two antigen binding sites. It is the most abundant immunoglobulin and is approximately equally distributed in blood and in tissue liquids, constituting 75% of serumimmunoglobulins in humans.[1] IgG molecules are synthesised and secreted by plasma B cells.
