摘要: A conjugate of an anti-HER2 antibody site-specifically modified with a peptide and a chelating agent. The chelating agent is chelated with a metal radionuclide, the peptide and the chelating agent are linked by a linker (L), and the linker (L) does not contain a thiourea bond. A radiopharmaceutical including the conjugate as an active ingredient.
