Fig 4. Effects of light-after treatment on eTE.

Fig 4

(a) PCI treatment was performed with the light-after protocol. All cells were exposed to light at 10 min post application of electric field. The treatment resulted in a significant reduction in eTE in COS7, HEK293 and HCT116 cells. (n = 4, *P<0.05, **P<0.01, Mann-Whitney U test.) (b) Dependence of eTE on the time of light treatment. Cells were divided into 7 groups. Cells in each group were exposed to light at a specific time points indicated in the horizontal axis of the plots, or not treated with light (NL). The eTE was quantified at 24 hours post electrotransfection. Each symbol in Panel (b) represents the mean eTE from two repeated experiments.
