HBV proteins and DNA levels of HepG2 cell supernatant.
HepG2 cells were transiently transfected with 10 μg pHBV4.1, pHBV-rtA181T/sW172* and pHBV-rtA181T/sW172L respectively. Cell supernatant was collected 3 days after plasmid transfection. (A) HBsAg levels in cell supernatant; (B) HBeAg levels in cell supernatant; (C) HBV DNA levels in cell supernatant. The mean and standard deviations of variables were also shown and they were obtained from three independent experiments. The P values were determined using Mann-whitney U test.
