Differences Between Antigen and Antibody
Antibodies, also called immunoglobulins, Y-shaped molecules are proteins manufactured by the body that help fight against foreign substances called antigens. Antigens are any substance that stimulates the immune system to produce antibodies. Antigens can be bacteria, viruses, or fungi that cause infection and disease.

1. Generally proteins but can be lipids, carbohydrates or nucleic acids.
2. Triggers the formation of antibodies.
3. There are three basic kinds of antigens. (Exogenous, Endogenous and Autoantigens)
4. The region of the antigen that interacts with the antibodies is called epitopes.
5. Cause disease or allergic reactions.
Antibody
1. Antibodies are proteins.
2. Variable sites has the antigen binding domain.
3. There are five basic kinds of antibodies. (Immunoglobulins M, G, E, D and A)
4. The variable region of the antibody that specially binds to an epitope is called paratope.
5. Protects the body by immobilization or lysis of antigenic material.
