At the molecular level, an antigen can be characterized by its ability to bind to an antibody's variable Fab region. Different antibodies have the potential to discriminate among specific epitopes present on the antigen surface. Hapten is a small molecule that changes the structure of an antigenic epitope. In order to induce an immune response, it has to be attached to a large carrier molecule such as a protein.
