Characterization of serum exosomes. (A) TEM images confirmed the presence of exosomes. Scale bar=200 nm. (B) Exosomes-enriched protein markers including CD9 and TSG101 were analyzed in exosomes (E) and exosome-depleted supernatant (EDS) by Western blot analysis. (C) The sizes of serum exosomes were determined via the NTA characterization system.
