Comparison of Hydrostatic Filtration Dialysis with Ultracentrifugation Methods for the Identification and Proteomic Profiling of Urinary Extracellular Vesicles.

BACKGROUND: Urinary extracellular vesicles (UEVs) carry rich markers of their parent cells, so they can serve as possible biomarkers of kidney diseases. METHODS: In this study, we isolated urinary extracellular vesicles from five individuals using a simple, clinically applicable method called hydrostatic filtration dialysis (HFD) and compared it to the gold-standard ultracentrifuga-tion (UC) with transmission electron microscopy (TEM). We also …
