Exosomes are produced by almost every cell type. They possess surface proteins (CD9, CD63 and CD81) that are specially enriched on the surface of these vesicles and are often used as biomarkers in research. 

Exosomes transfer specific biomolecules such as DNA, RNA, proteins, enzymes as well as lipids and thereby mediate cell-to-cell communication. After their release, they carry information to neighboring or distant cells. This intercellular vesicle traffic allows rapid and controlled communication and therefore plays an important role in many aspects of health and disease, including development, immunity, tissue homeostasis, cancer, and neurodegenerative diseases.

These products allow you to isolate exosome for research applications.
