将放射性核素标记到单抗 (Ｍｏｎｏｃｌｏｎａｌａｎｔｉｂｏｄｙ ,ＭｃＡｂ)上 ,利用单抗的肿瘤导向作用和放射性核素的细胞毒作用进行肿瘤的放射免疫治疗 ,是当今肿瘤核医学的主要研究方向之一。建立有效的放射免疫治疗方法首先考虑的是放射性核素的选择以及核素的辐射特性要
The radionuclide is labeled with a monoclonal antibody (McAb), and the radioimmunotherapy of the tumor using the tumor-directing effect of the monoclonal antibody and the cytotoxicity of the radionuclide is one of the main research directions of oncology nuclear medicine. The first consideration in establishing an effective radioimmunotherapy method is the selection of radionuclides and the radiometric properties of radionuclides.
