Abstract:
Objective With eukaryote expression vector pEGFP-C2, to establish the HepG2 cell line which may stably express the P22e of hepatitis B virus (HBV), and may be used to study the existed relationship between HBVP22e and hepatitis B. Methods HBVP22e cDNA obtained by PCR from HBV adr subtype 1.2 copies genome plasmid p3.8II was inserted into universal vector pMD18-T for identification. The plasmids were transfected into HepG2 cells via liposome, while EGFP-HBVP22e was analyzed by Western blot, and observed with fluorescence microscope in HepG2 cells. Results Expression vectors of recombinant pEGFP-C2HBV P22e were constructed and expressed steadily in HepG2 cells. Conclusion The results can be used to explore biological activity of HBVP22e in hepatitis B.
