Figure 3. Characterization of SEC-EVs and EXO-NET-enriched EVs included: (A) Quantification of protein content using the BCA assay; (B) Identification of CD9+ EV subpopulation; (C) Analysis of EVs spectra using FTIR; (D) Visualization of DiO-labeled EVs; (E) Selective EV surface marker profiles for SEC-EVs and EXO-NET EVs using a multiplex Exosome kit. Three dots indicate data from three donors. **P < 0.01 between SEC-EVs and EXO-NET EVs groups.
