【Abstract】 Objective To achieve highly specific monoclonal antibody against Nasopharyngeal Cancer (NPC). Methods Using Hunan NPC cell lines (HNE2) as immunogen, hybridoma cell lines were obtained through fusion of SP2/0 myeloma cells with immunized murine spleen cells by in vivo and vitro combining immunization. The positive clones were screened by an enzyme linked immunosorbent assay (ELISA) and indirect immunohistochemical method. Results Ten hybridoma cell lines secreting stable anti NPC monoclonal antibody were generated.As shown by indirect immunohistochemical detection, the percentages of positive reaction to NPC tissue samples were 60.0% for HNL1 and 65.0% for HNL5 respectively. Conclusion Anti NPC monoclonal antibody HNL1 and HNL5 exhibit fairly good specificity for NPC.更多还原
