This protocol describes the enrichment of astrocyte-derived extracellular vesicles (ADEVs) from human plasma. It is based on the separation of EVs by polymer precipitation, followed by ACSA-1 based immunocapture of ADEVs. Analysis of ADEVs may offer clues to study changes in inflammatory pathways of living patients, non-invasively by liquid biopsy.
