These types of antigens could possibly be large molecules observed around the surfaces of pathogens, but can even be little haptens (which include penicillin) connected to provider molecule.[60] Each and every lineage of B cell expresses a unique antibody, so the whole set of B mobile antigen receptors stand for many of the antibodies that the human body can manufacture.[57] When B or T cells encounter their related antigens they multiply and several "clones" in the cells are produced that concentrate on exactly the same antigen. This known as clonal variety.[sixty one]
