Abstract:
Objective In order to study the biological significance of HBV/C gene variant in vitro.Methods Retroviral vector pXT1 was used to construct the HBV/C gene expression vector and the recombinant plasmid pXT1-HBV/C was used to transfect immortalized human peripheral blood B cell lines to express HBcAg steadily in the host cells.Results plasmid pXT1-HBV/C was detected positive by PCR as well as enzyme digestion with Bgl Ⅱ and Xho Ⅰ.Meanwhile.transfected cells was detected to contain HBV/C gene by PCR and HBcAg was expressed in 47.4%of the ceils by means of flow cytometry.Conclusion Retroviral expression vector with HBV/C gene can transfeet into eucaryotic cells effectively and express the goal gene steadily.The recombinant cells may be used in the systematic studies on the biological significance of HBV/C gene variant.
