In principle, alpha-emitting radionuclides, such as 211At, are more efficient than beta-emitters to inactive single disseminated cancer cells. However, cellular processing of astatinated proteins has not yet been studied in detail. In this study an anti-colorectal cancer monoclonal antibody (mAb) A33 was indirectly labeled with 211At and for comparison with 125I. Binding and retention of radioactivity was studied in the colorectal cancer cell-line SW1222. A similar pattern of binding and retention of the two radiohalogens was seen. The main difference found, that the retention time of astatinated mAb in SW1222 was almost two times longer, might be of advantage in radionuclide therapy.
