摘要: 用SP2/0骨髓瘤细胞与日本血吸虫可溶性虫卵抗原免疫的BALB/C小鼠脾细胞融合,经筛选和克隆化后获得4株分泌抗血吸虫卵单克隆抗体的杂交瘤细胞.此4株单克隆抗体均能用虫卵抗原的ELISA、IHA和COP检出。用成虫冰冻切片作IFA可出现3种不同的免疫荧光反应类型。经交叉和吸收试验(ELISA法)证明其中3株对血吸虫卵具有高度特异性,另1株针对血吸虫、肺吸虫、华支睾吸虫共同抗原决定簇。4株单克隆抗体免疫球蛋白亚类鉴定均属小鼠IgM。

Abstract: After the fusion of SP 2/O myeloma cells with spleen cells of BALB/C mice immunized with SEA of Schistosoma japonicum eggs, 4 cell lines of hybridoma secreting monoclonal antibodies against S. japonicum eggs have been established. Four hybridoma-derived antibodies were measured by IFA with frozen sections of adult worms and 3 different patterns of immunofluorescence reaction were clearly revealed. Of these, 3 monoclonal antibodies presented a high specificity to SEA in ELISA and also showed positive COP and IHA reaction. Another monoclonal antibody was found to be against the common antigenic determinant of Schistosoma, Paragonimus, Clonorchis in I-ELISA, The immunoglobulin subclass of the 4 monoclonal antibodies were identified as IgM.
