Rhenium is one of the most valuable elements for internal radiotherapy because $$^{186/188}$$Re have favorable physical characteristics. However, there are problems when proteins such as antibodies are used as carriers of $$^{186/188}$$Re. Labeling methods require the complicated processes. Therefore, we planned the preparation by a simple method and evaluation of a stable $$^{186/188}$$Re-labeled antibody. For this purpose, we selected $$^{186/188}$$Re(I) tricarbonyl complex as a chelating site. A7 was used as a model protein. $$^{186/188}$$Re-labeled A7 was prepared by directly reacting a $$^{186/188}$$Re(I) tricarbonyl precursor with A7. $$^{186/188}$$Re-(CO)$$_{3}$$-A7 were prepared with radiochemical yields of 23-28%. After purification, $$^{186/188}$$Re-(CO)$$_{3}$$-A7 showed a radiochemical purity of over 95%. In biodistribution experiments, $$^{186/188}$$Re-labeled A7 showed high uptakes in the tumor.
