Detailed explanation-1: -the ability of the molecule to induce immune response. Immunogenicity of an antigen is determined by four properties; Foreigness, molecular size, chemical composition and heterogenicity and ability to be processed and presented on the surface of Antigen presenting cells (APCs).
Detailed explanation-2: -Antigens are substances (usually proteins) on the surface of cells, viruses, fungi, or bacteria. Nonliving substances such as toxins, chemicals, drugs, and foreign particles (such as a splinter) can also be antigens. The immune system recognizes and destroys, or tries to destroy, substances that contain antigens.
Detailed explanation-3: -The antigen should be a foreign substance to induce an immune response. The antigens have a molecular mass of 14, 000 to 6, 00, 000 Da. They are mainly proteins and polysaccharides. The more chemically complex they are, the more immunogenic they will be. Antigens are species-specific. More items •20-Sept-2020
