Exosome Purification

Introduction of Extracellular Vesicles (EV)

Extracellular vesicles (EVs) are subcellular components secreted by cells, which can carry many signaling molecules and participate in many physiological and pathological activities of the body. The detection and analysis of EVs and their contents is conducive to the analysis of diseases from the cellular, subcellular, and molecular levels, and is of great value to the basic research and clinical application of disease-related mechanisms.

Exosomes are EVs with diameters ranging from approximately 40 to 160 nm that contain many components of cells such as DNA, RNA, lipids, metabolites, cytosolic, and cell surface proteins. Apart from their potential therapeutic value, exosomes can also be used to diagnose diseases.
