Identification of exosomes extracted from the supernatant of H1299 cells. A Electron microscope was used to detect the morphology of exosomes. It could be seen that exosomes were saucer-like double concave disks. B The size of exosomes was analyzed by NTA particle size detection. The result showed that the highest exosome diameter was about 98 nm. C Western Blot was conducted to detect the expression of exosomes-related protein marker. The results showed that CD9 and TSG 101 proteins were positively expressed on exosomes, while Calnexin proteins were negatively expressed
