Construction of Recombinant Baculovirus Surface-Displayed the Capsid Protein of Porcine Circovirus Type 2
摘要
Abstract
The open capsid(Cap)protein gene without nuclear localization signal (NLS) of porcine circo-virus 2(PCV2)was amplified by PCR and sub-cloned into pBACsurf-1 between the upstream gp64 signal sequence and downstresm gp64 mature domain. The fusion gene containing dCap and gp64 was inserted into pcDNA3.1 ( + ) to construct the recombinant plasmid pcDNA3. L-gp64-dCap. A fragment of the CMV promoter-gp64-dCap fusion gene cassette was excised from pcDNA3. L-gp64-dCap and inserted into the baculovirus transfer vector pFastBac-V to construct the recombinant plasmid pFastBac-dCap-V. It was followed by the transformation of plasmid into Escherichia coli DHlOBac competent cells to obtain the recombinant shuttle vector Bacmid-dCap-V. Eventually, the recombinant Bacmid was transfected into Sf9 cells to produce the recombinant baculovirus Ac-dCap-V using the LipofectamineTM 2000. The Sf9 cells produced cytopathic after infection of recombinant baculoviruses Ac-dCap-V. Indirect immunofluoresent assay demonstrated that the Ac-dCap-V efficiently transducted the mammalian cells in vitro and the dCap protein was expressed successfully.关键词
