Abstract: A fragment of about 650 bp was amplified by RT-PCR technique with specific primers based on BVDV genome sequence. Then the target fragment was directionally cloned into pET32a vector. After identifying with enzyme cut and sequencing, the recombinant plasmid was transformed into E. coli BL21(DE3). The recombinant protein E0 was expressed in inclusion body form in E. coli after induction with IPTG. After purification, the purified protein was analyzed by Western blotting, the results showed that the purified recombinant protein retained better antigenicity.

Key words: bovine viral diarrhea virus; E0 gene; prokaryotic expression; characterization
