Figure 1. HBV persistence in mice induced by hydrodynamic injection of pGL3/Fluc-HBV1.2.

Figure 1

A. Titer of serum HBsAg in C57BL/6 or BALB/c mice after HBV plasmid injection. The detection limitation is 0.05 IU/ml. B. Serum HBV DNA levels in C57BL/6 or BALB/c mice after HBV plasmid injection. The detection limitation is 100 copies/ml. C. Bioluminescence image of C57BL/6 (H-2b) or BALB/c (H-2d) mice after hydrodynamic injection. D. Fluc expression in the liver and both serum HBsAg and HBV DNA levels showed strong linear correlation. E. Immunohistochemical staining for HBcAg in hepatocytes of HBsAg-positive C57BL/6 mice (magnification, 200x). In C57BL/6 mice, HBcAg-positive cells were maintained at stable levels on day 3 and day 135. F. Positive rate of serum HBsAg in C57BL/6 (n = 10) or BALB/c (n = 9) mice receiving injection with pGL3/Fluc-HBV1.2 at different time points after injection.
