title: [Establishment and identification of recombinant NS-1 cell strain that stably expresses chimeric HBc containing HBV multiepitope short peptides].
abstract: OBJECTIVE
  To establish recombinant NS-1 cell strain that is capable of stable expression of chimeric HBc particle containing HBV multi epitope short peptides.
  
  
  METHODS
  The recombinant plasmid, pHBc-Mep, was transfected into NS-1 cells via Lipofectamine, and the recombinant cell strain was screened with G418 and subclone screening. The expression products of the cells were examined by RT-PCR, ELISA, indirect immunofluorescence assay (IFA) and Western blotting.
  
  
  RESULTS
  The results of RT-PCR, ELISA, IFA and Western blotting demonstrated that the recombinant protein HBc-Mep was expressed in the screened cells after continuous cloning for 3 times, but not in cells transfected with pcDNA3.1 or nontransfected cells.
  
  
  CONCLUSIONS
  The recombinant cell strain stably expressing chimeric HBc particle containing multi epitope short peptides of HBV, designated as NS/HBc-Mep, has been established successfully.
