Zusammenfassung:	The present application relates to the technical field of biology, and in particular to an exosome cryopreservation protective liquid and a preparation method therefor. The exosome cryopreservation protective liquid comprises a Tris-HCl buffer solution containing NaCl and KCl, glucose, a CD-Lipid concentrate, a human serum albumin solution, and polyvinyl alcohol. The exosome cryopreservation protective liquid provided by the present application features rational proportioning, simple components, and clear composition; and an exosome added to the cryopreservation protective liquid can be stably preserved for 6-12 months at a low temperature of -20°C, and has biological activity kept to be 90% of its maximum activity. The cryopreservation protective liquid of the present application features clear composition of all components and cheap and easy-obtain raw materials, can be industrially produced, and has the advantage of low cost. La présente invention se rapporte au domaine technique de la biologie, et concern
