STORAGE STABILIZER FOR EXTRACELLULAR VESICLE AND STORAGE STABILIZATION METHOD FOR EXTRACELLULAR VESICLE

摘要

The present invention addresses the problem of providing a means capable of stably storing an extracellular vesicle. The present invention pertains to: a storage stabilizer which is for an extracellular vesicle and contains a copolymer having a monomer unit derived from vinyl pyrrolidone and a monomer unit derived from vinyl acetate, or a polymer having a monomer unit derived from vinyl pyrrolidone such as polyvinyl pyrrolidone; and a storage stabilization method which is for an extracellular vesicle and includes cryopreserving an extracellular vesicle in the presence of the polymer.
