Abstract

The idiotypic determinants of surface immunoglobulins on B-cell lymphomas and lymphocytic leukemias represent tumor-specific antigens, individually unique for each tumor. As such they have both diagnostic and therapeutic potential, particularly for those neoplasms with no serum monoclonal immunoglobulin arising from synthesis of the protein for export. We describe the raising in animals of anti-idiotype sera directed against two examples of a nonexporting neoplasm, human chronic lymphocytic leukemia. The procedure involves exposing the cells to papain so as to remove the Fab fragments (containing the idiotypic determinants) from the surface immunoglobulin, recovering the Fab on cellulose immunosorbent particles, and immunizing animals with the immunosorbent-Fab complex.

摘要

B细胞淋巴瘤和淋巴细胞白血病表面免疫球蛋白的独特型决定簇代表肿瘤特异性抗原,每个肿瘤都具有个体独特性。因此,它们具有诊断和治疗潜力,特别是对于那些没有因蛋白质分泌合成而产生血清单克隆免疫球蛋白的肿瘤。我们描述了针对非分泌型肿瘤(人类慢性淋巴细胞白血病)的两个实例在动物体内制备抗独特型血清的过程。该过程包括将细胞暴露于木瓜蛋白酶,以便从表面免疫球蛋白中去除Fab片段(含有独特型决定簇),在纤维素免疫吸附颗粒上回收Fab,并使用免疫吸附-Fab复合物免疫动物。
