[Preparation and characterization of monoclonal antibodies against Clonorchis sinensis]
Aim:
To develop and identify monoclonal antibody (McAb) against adult Clonorchis sinensis.
Methods:
BALB/c mice were immunized with soluble antigen of adult Clonorchis sinensis, the spleen cells of immunized mice were fused with myeloma cell line SP2/0. Then the hybridoma cell lines secreting high titer of McAbs were screened. The Ig subtypes and titer of the McAbs were assayed with ELISA. The antigens recognized by the McAbs were examined with IFAT and identified by immunoblot analysis. The cross reactions between the McAbs and antigens of Schistosoma japonicum, Paragonimus westermani and Cysticercus cellulosae were detected.
Results:
5 hybridoma cell lines secreting high titer of McAbs against adult Clonorchis sinensis were established. All five clones of McAbs belonged to IgM subtype. The antigens recognized by the McAbs were located at the intestinal tract wall of adult Clonorchis sinensis. The McAbs had no cross reactions with antigens of Schistosoma japonicum, Paragonimus and Cysticercus cellulosae.
Conclusion:
5 hybridoma cell lines against adult Clonorchis sinensis secreting high titer of McAbs with high specificity were established.
