The ORF of nsp2 gene was amplified by PCR from the nsp2 gene sequence of Group B rotavirus(GBRV).The PCR product was cloned into the expression vector pGEX-KG.After IPTG induction
the E.coli DH5α strain containing the recombinant plasmid expressed fusion protein with molecular weights of 61×10

which was in agreement with the prospectation.The purified recombinant protein was suitable to be used to immunize the mouse.Western Blot analysis using the multiclonal antibody derived from the mouse indicated that these antibodies could react with the target protein and were suitable to be used for further functional analysis of the nsp2 gene.
