FIGURE 1.

The transfection efficiency timeline of different cell lines according to the gene electrotransfer (GET) protocol. Percent of transfected B16F10 (A), C2C12 (B) and L929 (C) cells and fluorescence intensity of B16F10 (D), C2C12 (E) and L929 (F) cells. *p < 0.05, statistically significant difference in GET1/GET2 compared with GET4 (A); *p < 0.05, statistically significant difference in GET1/GET4 compared with GET3 and GET2 (B); **p < 0.05, statistically significant difference in GET2 compared with GET3 (B); *p < 0.05, statistically significant difference in GET1/GET2/GET4 compared with GET4 (D and E)

FIGURE 2.

Transfection efficiency of different pulse parameter protocols in three different cell lines. Percent of transfected tumor (B16F10) and normal (C2C12, L929) cells after GET1 (A), GET2 (B), GET3 (C) and GET4 (D) treatment. *p < 0.05 indicates a statistically significant difference; GET = gene electrotransfer
