WebClasses of Immunoglobulins. Antibodies are classified into five isotypes based on these heavy chains as IgM, IgG, IgA, IgE, and IgD, respectively. ... IgD is also present at low levels in the serum. However, IgD antibodies do not participate in the major antibody effector mechanisms, and the function of circulating IgD is mostly unknown. WebThere are five major classes of immunoglobulins - IgG, M, A, D and E. Each is made of two heavy and two light chains or polymers of this basic subunit. The structure of each heavy and light chain consists of a variable region involved in antigen specificity and binding and a constant region which is involved in the class specific properties.
