[Synthesis and identification of rutin complete antigen and analysis its immunogenicity].

OBJECTIVE

Synthesis and identification of complete antigen of rutin, the traditional Chinese medicine active ingredient, and develop rapid detection of rutin using enzyme-linked immunoassay method (ELISA). Immunogenicity of the complete antigen was also studied.

METHOD: Prepare the complete antigen by sodium periodate solution and identified by UV scanning and SDS-PAGE test. Male New Zealand white rabbits were immunized by the antigen to obtain the antiserum.

RESULT: The results of UV analysis showed that the coupling ratio of complete antigen is 13: 1. SDS-PAGE display of the artificial antigen was delayed compared with bovine serum protein. The titer of rutin antibody is 1:4 000. The sensitivity of IC50 was 5.37 mg x L(-1), the lowest detection limit was 1 mg x L(-1), the average recovery was 102%, the intra and interspecific RSD were less than 10%, cross-reactivity rate of antibodies and other analogs were less than 1%.

CONCLUSION

Rutin complete antigen was synthesized successfully, and the rapid detection of rutin by ELISA method was successfully established.
