Characterization of isolated plasma exosomes. (A) TEM image showed representative data of exosomes with a diameter of 50-150 nm isolated from the plasma of NSCLC patients. (scale bar: 100 nm; high voltage (HV) = 80 kV). (B) Plasma exosome diameter detection based on qNano system, with diameters mainly distributed in the range of 70-150 nm (C) Western blot analysis of cell protein markers: GM130, and exosomal protein markers: CD9 and HSP70.
