ABSTRACT
Objective To express VP1recombinant protein of Echovirus 30 (ECHO30) in E.coli BL21(DE3) and to develop an enzyme-linked immunoassay (EIA) based on the recombinant antigen for detecting antibodies to ECHO30.Methods The target VP1gene was amplified by reverse transcription-polymerase chain reaction (RT-PCR).The PCR products of the gene were inserted into pET44a vector,and then expressed in E.coli BL21( DE3 ).The purified recombinant protein was used for the development of EIA.Results The molecular weight of the recombinant protein was 95 000,and the antigenicity of which was identified by Western blot and EIA.Conclusion The recombinant protein VP1has been successfully expressed and purified,which can be used as diagnostic antigen.
