J chain is a small, glycopeptide of 15 kD. It is structurally unrelated to heavy or light chains, but is synthesized by all plasma cells that secrete polymeric immunoglobulins. J chains are present in a large proportion of the immunoglobulin-positive cells in the germinal centers of the tonsils and lymph nodes. B cells secrete J chain at an early stage of differentiation with the expression persisting in those cells destined to produce IgA or IgM. J chain has been proposed to play a role in the mucosal transport of polymeric Igs by the polymeric Ig receptor. The studies show that a significant proportion of deposited mesangial immunoglobulin in IgA nephropathy is dimeric, or J chain positive. This monoclonal antibody stains J chain in cytoplasm of positve cells.
