The analysis method for extracellular vesicles, according to the present invention, uses the size-specific separation ability of size exclusion chromatography and the properties of a probe that specifically binds with extracellular vesicles, and by using same is capable of the rapid and easy analysis of the quantity of extracellular vesicles included in a sample, analysis of the physicochemical properties of the extracellular vesicles, analysis of the kind and quantity of the components included in the extracellular vesicles, and analysis of the binding properties or affinity of the probe with respect to the components of the extracellular vesicles. In addition, using the analysis method of the present invention not only enables accurate analysis of extracellular vesicles in a sample, without a sample purification or pre-processing step, but also enables accurate and simple analysis of the components of extracellular vesicles, according to the kind of probe, and thus can improve the efficiency of diagnosis using extracellular vesicles. Also, analysis of the properties or affinity of the probe can be applied to, for example, extracellular vesicle-specific antibody screening, protein screening and chemical-substance screening.

Analysis method for extracellular vesicles, using size exclusion chromatography, and use for same

An extracellular vesicle isolation method using a metal, and a method for isolating extracellular vesicles from various samples using metal affinity are disclosed. An extracellular vesicle isolation method 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 can be combined with existing isolation methods to maximize the efficiency of extracellular vesicle isolation, and can be utilized in disease diagnosis, disease treatment, multi-omics research, and extracellular vesicle property research and the like using the isolated extracellular vesicles.
