In the cationic state astatine forms a stable complex with diethylenetriaminepentaacetic acid. Thanks to this complex, astatine can be bound to monoclonal antibodies of the RYa{sub 1} type. The most favorable conditions for preparing astatine-labeled antibodies are established. The chromatographic analysis and electromigration experiments showed that astatine is firmly linked to a biomolecule in vitro and it did not escape from labeled monoclonal antibodies even under treatment with such highly effective astatine-complexing agent as thiourea. The immune activity of astatine-labeled antibodies did not change even after 20 h.
