212Bismuth Linked to an Antipancreatic Carcinoma Antibody: Model for Alpha-Particle-Emitter Radioimmunotherapy

Abstract
For comparison of cytotoxicity from alpha-particle irradiation with that from conventional x-irradiation, 212Bi, an alpha-emitting ra-dionuclide, was attached to a monoclonal antibody that recognizes a cell surface antigen on human pancreatic carcinoma cells. For a given level of survival, the 212Bi-antibody
