iodine I 131 tositumomab

A monoclonal antibody directed against the CD20 protein expressed on the surface of B-lymphocytes and radiolabeled with the radioisotope iodine I 131 with potential antineoplastic activity. Iodine I 131 tositumomab binds to and selectively delivers cyctotoxic radiation to CD20-expressing B-lymphocytes, thereby minimizing systemic radiotoxicity.
