[fifty nine] In contrast, the B mobile antigen-certain receptor is surely an antibody molecule within the B mobile floor and recognizes indigenous (unprocessed) antigen with no will need for antigen processing. Such antigens might be substantial molecules located within More hints the surfaces of pathogens, but can also be compact haptens (for instance penicillin) attached to provider molecule.[sixty] Each lineage of B cell expresses a distinct antibody, so the entire list of B mobile antigen receptors represent each of the antibodies that your body can manufacture.[fifty seven] When B or T cells come upon their similar antigens they multiply and several "clones" from the cells are manufactured that target the exact same antigen. This is named clonal range.[61]
