Abstract: One pair of specific primers was designed according to the sequence of PRRSV ORF3 gene published inCnBank(Accession number PRU87392),and was used to ampl the ORF3 gene from a PRRSV Hn 1/ 06 strain by RT-PCR method,resulting in a 765 gene fragment. The RT-PCR product was directly cloned into the pTG19-T vector andthe recombinant plasmid was identified by enzyme digesting and DNA sequencing. The positive clone was designated asp TG19- T-GP3.After being cloned into the prokaryotic expression vector pET-32a,the ORF3 gene was successfully ob-twined by the induction of IPTG. Western blot test confirmed that the expressed fusion protein could specifically react withthe antiserum against PRRSV. It could be used for the further investigation on immunogenicity and function of GP3 of PRRSV.
