Exosome Isolation From Cell Culture Media Protocol

This chapter describes a detailed protocol for isolating exosomes from cell culture conditioned medium using ultracentrifugation and their characterization based upon size number and protein expression by several complementary methods such as transmission electron microscopy nanoparticle tracking analysis western blotting and flow cytometry.
