Abstract

A primary human osteogenic sarcoma was visualized in situ by external gamma-camera imaging following administration of 131I-labelled anti-osteogenic sarcoma monoclonal antibody 791T/36. A xenograft of the tumour established in immunodeprived mice also showed localization of 131I-791T/36 determined by both gamma-camera imaging and organ distribution studies. Radiolabelled normal immunoglobulin showed no tumour localization. Expression of the 791T/36-defined antigen on xenografted tissue was further confirmed by reaction of its in vitro-cultured cells with fluorescein-labelled 791T/36 antibody.

摘要

在给予¹³¹I标记的抗骨肉瘤单克隆抗体791T/36后,通过外部γ相机成像对原发性人骨肉瘤进行了原位可视化。在免疫缺陷小鼠中建立的肿瘤异种移植模型,通过γ相机成像和器官分布研究确定,也显示出¹³¹I-791T/36的定位。放射性标记的正常免疫球蛋白未显示肿瘤定位。通过体外培养细胞与荧光素标记的791T/36抗体反应,进一步证实了791T/36定义的抗原在异种移植组织上的表达。
