Analysis of eEVs purified further by Size Exclusion Chromatography (SEC) following TFF concentration. 1 mL of TFF (between 50 and 650 nm) isolated EVs were loaded into the SEC column. Each 1 mL fraction was collected and analyzed. A Particle concentration and Protein concentration of Naïve EVs (B) Particle concentration and protein concentration of engineered EVs (RDG-EVs). C Particle concentration and protected DNA amount of engineered EVs (RDG-EVs). This experiment was performed n = 3, and one of the data was presented. D Particle concentration and protected DNA amount of engineered EVs (RDG-EVs) that were isolated by Ultracentrifugation and SEC
