The gamma-globulin fraction contains the immunoglobulins, a family of proteins that function as antibodies.
Antibodies, in response to infection, allergic reactions, and organ transplants, recognize and bind foreign bodies, or antigens, to facilitate their destruction by the immune system. The immune response is regulated by a large number of antigen-specific gamma-globulins that fall into five main classes called IgG, IgA, IgM, IgB, and IgE.
Normally there is no, or only a small amount, of protein in the urine. When there is protein in the urine, it normally consists of mainly albumin.
