Abstract |
Extracellular vesicles (EVs), including exosomes are endocytically derived nanovesicles expelled from cells that contain molecular information in the form of lipids, proteins, and nucleic acids. Transfer of this information to other cells in local or distant microenvironments facilitates cell-to-cell communication. Importantly, diseased cells release exosomes containing specific cargo that may contribute to pathology and can be harnessed for diagnostic or prognostic use. The broad potential medical utility of exosomes has fueled rapidly expanding research on understanding the composition and functions of exosomes in normal and pathological conditions. Here, we provide a complete workflow for purifying exosome-sized vesicles from biological fluids for in-depth proteomic analyses. Moreover, this polyethylene glycol-based method is efficient, highly adaptable, and compatible with a variety of downstream applications. |
