The application is drawn to radiolabeled biomolecules and methods for radiolabeling biomolecules with radioactive halogen atoms that minimizes loss of the radioactive halogen due to dehalogenation in vivo, preserves the biological activity of the biomolecule, maximizes retention of radioactivity in cancer cells, and minimizes the retention of radioactivity in normal tissues after in vivo administration. Some such radiolabeled biomolecules comprise a radioactive metal atom in place of, or in addition to the radioactive halogen. The biomolecules have an affinity for particular types of cells and may specifically bind a certain cell, such as cancer cells. Relevant biomolecules include antibodies, monoclonal antibodies, antibody fragments, peptides, other proteins, nanoparticles and aptamers.
该应用程序涉及放射性标记的生物分子和使用放射性卤素原子对生物分子进行放射性标记的方法,从而最小化由于体内脱卤而导致的放射性卤素损失,保留生物分子的生物活性,最大限度地保留癌细胞中的放射性活性,并在体内给药后最小化正常组织中的放射性活性保留。一些这样的放射性标记的生物分子包括放射性金属原子代替或附加在放射性卤素原子上。这些生物分子具有亲和力,可以特异性地结合某些细胞,例如癌细胞。相关的生物分子包括抗体、单克隆抗体、抗体片段、肽、其他蛋白质、纳米颗粒和适配体。
