Validation of human exosome purification. a Scanning electron micrograph of exosomes purified from human plasma. Scale bar, 200 nm. n = 4 biological samples. b Atomic force microscopy amplitude trace of exosomes purified from human plasma. Size range, 63–105 nm. Scale bar, 500 nm. n = 7 biological samples. c Representative nanoparticle tracking analysis of exosomes purified from human plasma. N = 4 biological samples. d Western blot analysis of control (Cntl) and patient (Pt) exosomes (exos). Western blots have been cropped for clarity and conciseness.
