The immunological similarity of rat glandular kallikreins

Abstract
The immunological properties of the submandibular kallikrein, urinary kallikrein, pancreatic kallikrein and pancreatic prekallikrein of the rat were studied by immunodiffusion, immunoelectrophoresis and radioimmunoassay. Although they behaved differently electrophoretically, all the antigens showed identical immunological behaviour. The implications of this are discussed.
