Design of antigen synthesis and identification of its artificial antigen for zearalenone
Background: study aimed to modify the ZEN molecule and conjugate the carrier protein to prepare a complete antigen. To lay the foundation for the preparation of ZEN monoclonal antibodies. Methods: The carbonyl group at the 7 position of ZEN molecule was modified by deuteration reaction. The immunogen and antigen were synthesized by EDC method and mixed acid anhydride method, and the complete antigen was identified by UV, IR and electrophoresis. Antisera were obtained after immunization of animals, and an antiserum was designed by ELISA. Results: The immunogens were identified by UV, IR and electrophoresis, ZEN-BSA was successfully synthesized. The ratio of ZEN-BAS to ZEN was calculated to be 1 : 13. When the antibody serum was detected, the titer of the antibody reached 1:(6.4×103). Conclusion: This study demonstrated that the OAE method is preferable in preparing the ZEN. These findings lay the material and technical foundation for the preparation of anti-ZEN monoclonal antibody
