Title:
EXTRACELLULAR VESICLE ISOLATION METHOD USING METAL
Document Type and Number:
WIPO Patent Application WO/2018/131966
Kind Code:
A1
Abstract:
The present invention relates to an extracellular vesicle isolation method using a metal, and more particularly, relates to a method for isolating extracellular vesicles from various samples using metal affinity. An extracellular vesicle isolation method according to the present invention has the advantages of not requiring costly equipment, of being able to be applied without limits on sample quantity, and of being capable of efficiently isolating extracellular vesicles while preserving the shape or properties thereof. Moreover, the method of the present invention can be combined with existing isolation methods to maximize the efficiency of extracellular vesicle isolation, and can be utilized in disease diagnosis, disease treatment, multiomics research, and extracellular vesicle property research and the like using the isolated extracellular vesicles.
