Schematic summary of standard laboratory methods for exosome purification. Four different isolation techniques are demonstrated here: Polymeric precipitation¹¹⁶, (top left), column for size exclusion chromatography¹²³, (top right), density gradient chromatography¹¹⁰, (bottom right) and differential ultracentrifugation¹¹⁰, (bottom left). Temperature maintained at 4°C for most of the protocol¹¹⁰.
