Characterization of serum exosomes. (a) TEM images indicating the characteristic data of exosomes with a diameter of 50–150 nm in NSCLC patients. (b) The exosomes with a size range of 50–150 nm were analyzed by the qNano system. (c) The exosomal protein markers, such as CD54, CD9, and GM130, were detected in the serum by western blotting analysis.
