    Isolation of exosomes from human serum The initial volume of serum for the experiments was 4 mL per sample. The samples were diluted with an equal volume of PBS (AppliChem‚ St. Louis‚ MO) to decrease the viscosity. The diluted serum samples were centrifuged at 2‚000×g for 10 min and 10‚000×g for 30 min at 4 °C to remove dead cells and cell debris. The supernatant was transferred into Ultra-ClearTM tubes (Beckman Coulter‚ Indianapolis‚ IN) and centrifuged at 100‚000×g using a Beckman Optima XL-70
