Abstract
Exosome purification methods involve use of a whey composition as an exosome source. Exosomes are isolated by subjecting the whey composition to a first ultrafiltration, which yields a first permeate and a first retentate. The first retentate may then be subjected to a second ultrafiltration, yielding a second permeate and a second retentate. During the second ultrafiltration, the first retentate may be treated with carbon dioxide. The second retentate may then be subjected to a third ultrafiltration, yielding a third permeate and a third retentate. The third permeate may then be optionally dried to yield an exosome powder.
