From: The impact of impaired DNA mobility on gene electrotransfer efficiency: analysis in 3D model
The effect of different modes of DNA administration on gene electrotransfer efficiency (left). Cells were embedded in a collagen gel and DNA was administered: on top of 3D model (A-right) or injected into the 3D model (B-right). The percentage of transfected cells is plotted for different electric pulses: 8 × 1 ms and 8 × 2 ms pulses of various electric field strength E (kV/cm). In all experiments, the same amount of pDNA was administered (18.2 μg). Values represent means (all tests were performed in triplicate) and error bars are determined from standard deviation. Results were considered as statistically different when p < 0.05
