||Commonly called “antibodies generating chemicals” or immunogens.
||Commonly called immunoglobulins.
||Both proteinous or polysachharides.
||Always proteinous in nature.
||They are present on the cell membrane.
||They are present in the plasma.
||These stimulate the immunity of the body.
||These protect the body from infections.
||May be a foreign substance or produced by the body itself.
||They are always produced by the body.
||They induce the production of antibodies.
||They inactivate the antigen.
||The four types include exogenous antigens, endogenous antigens, autoantigens and neoantigens.
||The five types include IgM, IgG, IgD, IgA, IgE.
||The part of antigen that combines with antibody is called epitope.
||The part of antibody that recognizes the epitope is called paratope.
||High complexity in structure (simple to complex).
||‘Y’ shaped structure with four polypeptide chains.
||Cause disease or allergic reactions.
||Protects the body by immobilization or lysis of antigenic material.
