本文综述对放射性核素的某些研究和抗体标记的化学,并讨论了放射标记的抗体用于诊断和治疗的某些展望。供体内诊断用的放射标记的抗体这种抗体应能定位于肿瘤组织中,理想的放射性核素应:(1)有很多100～200KeV之间的光子;(2)物理半衰期与要研究的生物过程相似; This article reviews some of the studies on radionuclides and the chemistry of antibody tags, and discusses some of the promise of radiolabeled antibodies for diagnosis and treatment. Radiolabeled antibodies for in vivo diagnosis should be able to localize in tumor tissue. The ideal radionuclide should: (1) have many photons between 100 and 200 KeV; (2) physical half-life and the organism to be studied The process is similar;
