Figure 4

Optical (left) and fluorescent (right) images of HEK293T cells transfected with plasmid EGFP using (a–f) PEI_60kD at N/P = 80 and (a'–f') PEI_25kD at N/P = 160, at a post transfection time of 48 h. EV solution of different volume (0, 0.5, 1, 2, 5, and 10 μL) were added into each well of the 96-well plate for images (a–f) and for (a'–f'), respectively. The protein concentration in EV solution was 3 ng/μL⁻¹ All the images were taken at the same exposure time (500 ms).
