An antigen is a substance or molecule that, when introduced into the body, triggers the production of an antibody by the immune system, which will then kill or neutralize the â¦ antigen that is recognized as a foreign and potentially harmful invader.
1 Antigens are proteins and other macromolecules that bind to a specific antibody and are used by the immune system to recognize pathogens.  B cells express receptors (BCRs) on their membrane which contain antibodies; these antibodies allow B cells to detect pathogens and release further antibodies to fight the infection.
