Episomal rAAV-mediated gene repair. (A) HEK293T cells were infected with an increasing multiplicity of infection (MOI) of the rAAV2/1-GFPLuc vector following (dark grey bars) or not (white bars) a transfection step with the target vector peGFPLucMut. Two days after, cell samples were submitted to luciferase activity measurement to quantify the gene repair efficiency (left y-axis). Total protein content is shown on the right y-axis (squares for repair conditions and triangles for the control experiments). (B) Similar experiment as in (A) conducted with the target vector pmeGFP followed by eGFP positive cells counting to determine the repair frequency.
