Abstract
The present disclosure relates to multistep chromatographic methods for preparing extracellular vesicles (EVs). The methods were demonstrated to be effective in preparing highquality EVs in a large scale. The methods enable preparation of EVs for therapeutic and diagnostic applications, and isolation and/or sub-fractionation of EVs with desired properties for specific use.
