[Experimental study of the murine monoclonal antibodies of anti-human osteogenic sarcoma]
1Xijing Hospital Fourth Military Medical University, Xian.
In the present experiment, cellular suspension, extracted from osteogenic sarcoma tissue removed from patients in operation, was used to immunize BABL/cmouse. The immunized murine spleen cells and murine myeloma cells were fused. The three lines of the hybridoma cells were produced by fusion and were screened by the method of PAP immunoperoxidase. Three hybridomas (MOG 1, MOF 6, MoC 4) reacted with osteogenic sarcoma but not with the normal synovium. MOF 6 reacted with rhabdomyosarcoma, fibrosarcoma, undifferentiated round cell sarcoma and melanoma but not with other tumors and normal tissues. MOG 1 and MOC 4 reacted with more tumors and tissues. The subclasses of MOF 6 and MOG 1 were identified. Both antibodies are IgG 1. Ascites developed in 10 days after two hybridomas were injected respectively into the murine peritoneal cavities. By more extensive research, the monoclonal antibodies may be used in many clinical and experimental works.
