Monoclonal antibodies and fragments thereof, hybrid cell lines producing these antibodies and methods of using them are described. They are characterized in that they
- belong to Cluster w4 as defined at the International Workshop on SCC, London 1987,
- show high capacity for in vivo localisation,
- have low retention in non-target organs,
- exhibit persistence at the target tumor and
- bind to a glycoprotein antigen having the following characteristics:
- molecular weight of approximately 45000 before and about 15000 to about 17000 after deglycosylation;
- remains reactive with antibody SWA11 after deglycosylation;
- remains present in cells after treatment with tunicamycin.
They have an interesting pharmacological activity and may thus find application in the diagnosis and/or treatment of lung carcinoma.
本文描述了单克隆
抗体及其片段、产生这些
抗体的杂交
细胞系以及使用它们的方法。它们的特点是
- 属于 1987 年伦敦 SCC 国际研讨会定义的 w4 群、
- 体内定位能力强、
- 在非靶器官中的存留率低、
- 在靶肿瘤中表现出持久性
- 与具有以下特征的糖蛋白抗原结合:
- 脱糖前分子量约为 45000,脱糖后分子量约为 15000 至 17000;
- 脱糖后仍与
抗体 SWA11 反应;
- 用曲奈霉素处理后仍存在于细胞中。
它们具有有趣的药理活性,因此可用于诊断和/或治疗肺癌。
