Figure 2

In vitro delivery efficiency of FNP–siRNA in two cell lines. (A) Delivery efficiency in H. armigera Ha cells. (B) Delivery efficiency in H. armigera Ep cells. 1F, 2F, and 3F indicate FNP:siRNA amount ratios 1:1, 2:1, and 3:1, respectively. Data are mean ± SD. Asterisks “**” and “*” indicate significance at p < 0.01 and p < 0.05 levels, respectively. After 6–24 h transfection in darkness, fluorescence in FNP-siRNA transfected cells was imaged. The delivery efficiency was calculated as the percentage of fluorescent cells to total cells.
