Explanation:
Detailed explanation-1: -Antigen: definition An antigen is any foreign substance that can elicit an immune response in the body (eg, antibody production) and is bound by the specific antibodies produced against it by the immune system. Antigens generally have high molecular weight and are commonly proteins or polysaccharides.
Detailed explanation-2: -An antigen is a foreign or “non-self” macromolecule that reacts with cells of the immune system. Not all antigens will provoke a response. For instance, individuals produce innumerable “self” antigens and are constantly exposed to harmless foreign antigens, such as food proteins, pollen, or dust components.
