The present invention provides a metal ion scavenging procedure and antibody compositions for radioimmunoscintigraphy and cytotoxic radioimmunotherapy having chelator concentrations of greater than about 10⁻⁴ M which are optimized with respect to their metal binding capacity such that highly efficient labelling of the antibody is achieved in a simple one step procedure using readily available sources of radiometal ions.
本发明提供了一种
金属离子清除程序和用于放射免疫镜成像和细胞毒性放射免疫疗法的
抗体组合物,其
螯合剂浓度大于约 10-⁴ M,在
金属结合能力方面进行了优化,这样就可以使用现成的放射性
金属离子源,通过简单的一步程序实现
抗体的高效标记。
