Outline of Final Research Achievements |
To realize radioimmunotherapy using a promising alpha-emitter 211At, we investigated the synthesis method of 211At-labeled antibody and its biodistribution and tumor accumulation properties. Also, the 64Cu-PET imaging method was examined its availability for estimating the 211At-antibody biodistribution. We succeeded to obtain a 211At-antibody with high blood retention and tumor accumulation properties comparable with 64Cu-antibody by using a PEG containing linker to reduce the hydrophobicity after 211At labeling.
