  • Publication number: 20220220043
    Abstract: The present invention relates to a method for radioiodination or radioastatination of a biomolecule such as proteins and antibodies by reacting a biomolecule carrying a hetero(aryl) boronic acid group with a radioiodide or astatide salt, in the presence of a catalyst and a ligand, in a buffer solution, in order to obtain a radioiodo- or astatolabeled biomolecule. The method of the invention is thus a single step method easy to be implemented and efficient for both radioiodination and radioastatination of antibodies.
