Extracellular vesicles (EVs), are membrane-bound nanoparticles of biological origin. These signature molecules of health and disease have raised remarkable attention of the biomedical arena due to its potential diagnostic and therapeutic applicability. Among the many different techniques available for EV isolation, size-exclusion chromatography (SEC) is widely accepted.In this chapter, we present a protocol of size-exclusion high-performance liquid chromatography (SE-HPLC) as a method of EV isolation. This method can be adapted as a low cost but a reliable and scalable method of EV isolation in those laboratories having access to the HPLC systems.
