Figure 5From: Key elements of the human bocavirus type 1 (HBoV1) promoter and its trans-activation by NS1 proteinComparative analysis of luciferase activity following recombinant plasmids (P1-P8) transfection in HeLa cells. The cells were harvested at 48 h post-transfection and the luciferase assay was performed as described in the Methods section. The error bars indicate standard deviations of three independent experiments and each performed in triplicate. Co is control value from pGL3-Basic.Back to article page
