The HBV X gene was amplified by PCR according to the pecob6 containing the whole fragment of adw subtype of HBV, then the fragment was inserted into the multiple clone site of pAdTrack-CMV. The linearized shuttle plasmid was homogenously recombined with AdEasy-1 in BJ5183 and the recombinant adenoviral plasmid pAd-X was generated. Then plasmid pAd-X was digested with Pac I and transfected into 293 cells for packaging and amplifying. Infection titer and rate were monitored by green fluorescent protein (GFP) expression. With restriction endonuclease analysis and PCR methods, it has been confirmed that HBV X gene was cloned into the adenovirus vector successfully. The expression of X protein in HepG2 cells was detected by Western-blot. The recombined adenovirus Ad-X was constructed successfully, which would contribute to the advanced functional study of HBV X protein.
