Antigens are large molecules, usually proteins, on the surface of cells, viruses, fungi, bacteria, and some non-living substances such as toxins, chemicals, and foreign particles.Any substance capable of triggering an immune response is called an antigen.kip to content. Antibodies, also called immunoglobulins, are large Y-shaped proteins which function to identify and help remove foreign antigens or targets such as viruses and bacteria.
Infection with viruses or bacteria triggers the immune system to release proteins called antibodies.

Once produced by the body (specifically, by the lymphoid tissue, which is part of the body's immune system), antibodies circulate in the bloodstream until they come into contact with an antigen.
