title: [The expression and bioactivity of S gene in Vero-E6 cells using baculovirus vector].
abstract: OBJECTIVE
  The S gene of a Hanta Virus (HV) Z10 strain was cloned into a baculovirus shuttle bacmid pDual-CMV contained a CMV promoter to generated a recombinant baculovirus BAC-pDual-CMV-HVS, then the recombinant baculovirus was transfected into Vero-E6 cell. The cells with recombinant baculovirus were applied to the detection of HV antiserum.
  
  
  METHODS
  To generate the recombinant baculovirus BAC-pDual-CMV-HVS, the sequence of CMV promoter was obtained from the plasmid pEGFP-N1 by PCR, and subsequently cloned to the baculovirus shuttle bacmid pFastBacDUAL resulting the recombinant plasmid pDual-CMV. Then the sequence of HV-S gene was inserted to the plasmid pDual-CMV, to generate the plasmid pDual-CMV-HVS. Plasmid pDual-CMV-HVS was transformed into the DH10BAC competent cells to get the recombinant baculovirus BAC-pDual-CMV-HVS. The antigen substrate slides were made by transfecting the recombinant virus into Vero-E6 cells.
  
  
  RESULTS
  The plasmid pDual-CMV-HVS was verified by sequencing. The recombinant virus BAC-pDual-CMV-HVS was generated according to the protocol of the baculovirus and transfected into Vero-E6 cells. The expression of the HV-S gene was verified by positive HV antiserum.
  
  
  CONCLUSIONS
  [corrected] The recombinant virus were successfully generated and applied to prepare the antigen substrate slides. The antigen substrate slides was conveniently prepared without special equipments, and can be used to detect the antiserum of HV virus.
