Differences between antigens and antibodies
March 11, 2018
S.N | Antigens | Antibodies |
1. | Commonly called “antibodies generating chemicals” or immunogens. | Commonly called immunoglobulins. |
2. | Both proteinous or polysachharides. | Always proteinous in nature. |
3. | They are present on the cell membrane. | They are present in the plasma. |
4. | These stimulate the immunity of the body. | These protect the body from infections. |
5. | May be a foreign substance or produced by the body itself. | They are always produced by the body. |
6. | They induce the production of antibodies. | They inactivate the antigen. |
7. | The four types include exogenous antigens, endogenous antigens, autoantigens and neoantigens. | The five types include IgM, IgG, IgD, IgA, IgE. |
8. | The part of antigen that combines with antibody is called epitope. | The part of antibody that recognizes the epitope is called paratope. |
9. | High complexity in structure (simple to complex). | ‘Y’ shaped structure with four polypeptide chains. |
10. | Cause disease or allergic reactions. | Protects the body by immobilization or lysis of antigenic material. |
