The RI-labeled anti-MUC5AC humanized antibody of the present invention is a complex of a chelating agent in which a radionuclide is chelated and an antibody (the radionuclide is a metal nuclide that emits [alpha]-rays or positrons, and the antibody is a humanized antibody that specifically binds to MUC5AC) and is very useful for treating and/or diagnosing diseases in which MUC5AC is overexpressed, and especially cancers, since it is excellent in specificity for MUC5AC and accumulation in tumors. |
