Astatine-211 labeling: a study towards automatic production of astatinated antibodies

Targeted alpha therapy is especially interesting for therapy of microscopic cancer tumors due to short path length and high linear energy transfer of the alpha particles. One of the most promising nuclides for targeted alpha therapy is At-211. To facilitate larger clinical studies using At-211, the current manual synthesis of radiolabeled antibodies would benefit from being transferred into an automated method. In this work, successful modifications of the manual synthesis have been performed in order to adapt it to automation. The automatic synthesis has also been tested using the modified synthesis method.
