Identification of plasma-extracted exosomes. Identification of plasma-extracted exosomes. A. Transmission electron microscopy showed the morphological characteristics of exosomes. White arrows represent tipical exosomes in a single field of view under TEM, Scale bar =200 nm. B. Use a nanoparticle size analyzer to detect exosome size. C. Verification of exosomal surface marker protein by Western blotting, Exo represents the exosomal sample and negative control representing the supernatant when the exosomes are extracted.
