抗人黑色素瘤单克隆抗体在荷瘤裸鼠体内的分布及其定位显像

Biodistribution and radioirnmunoimaging of monoclonal antibody to human melanoma in tumor-bearing nude mice

本文观察了^(131)I 标记的黑色素瘤 McAb HB8759在荷瘤裸鼠体内的生物学分布及放射免疫显像。静脉注射 ^(131)I—McAb48h 和72h 后肿瘤与非肿瘤在5种主要脏器比活性比值(T/NT)分别平均为6.6和9.6,^(131)I—McAb 注射24h 后在移植瘤中明显定位浓集,48～72h 是放射免疫显像的最佳时间。

Biodistribution and radioimmunoimaging of monoclonal antibody HB8759 agaist human melanoma in tumor-bearing nudemice were investigated.The results showed that mean tumor: nontumor(5 main organs)ratios were 6.6 and 9.6 at 48 and 72hr after injection of the ^(131)Ⅰ—McAb,respectively,and tumor was clearly visualized under ECF at the same time.It is suggested that McAb HB8759 is a potential biologic product for diagnosis of metastic melanoma and intraocularmelanoma and clinical treatment of melanoma.
