The Dual-luciferase activity of the eukaryotic expression plasmid transfected HepG2 cells.
(A) the relative luciferase activity of CpLUC; (B) the relative luciferase activity of PS1pLUC; (C) the relative luciferase activity of SpLUC (D) the relative luciferase activity of XpLUC. The mean and standard deviations of relative luciferase activity were also shown and they were obtained from three independent experiments. The P values were determined using Mann-whitney U test.
