Figure 2From: Direct visualization of electroporation-assisted in vivo gene delivery to tumors using intravital microscopy – spatial and time dependent distribution Comparison of transfection efficiency between tumour center and periphery following two different electroporation protocols GFP expression in rat P22 tumor growing in rat dorsal flap window chamber 2 days after two different electroporation conditions: EP1: 8 electric pulses, 600 V/cm, 5 ms, 1 Hz (a, c); EP2: 8 electric pulses, 1300 V/cm, 0.1 ms, 1 Hz (b, d). Comparison of transfection efficiency in the ROI's of tumor center (a, b) and periphery (c, d) (x10 objective). Arrows: edge of the tumor.Back to article page
