Figure 4. In-vitro expression levels of luciferase reporter protein.

Cb cells were transfected with pGL3-PEI-coated nanoparticles. The graph shows the percentage of positive wells showing luminescence on day 2, 3, 4 after washing the nanoparticles off. Well values higher than negative control average + 3x standard deviation, were considered positive. Results are shown as mean ± S.E.M. (n = 48).
