Preparation of Multi-omics Grade Extracellular Vesicles by Density-Based Fractionation of Urine.

The multidimensional cargo of extracellular vesicles (EV) released in urine is a reflection of the pathophysiological processes occurring within their cells and tissues of origin in the urogenital system. Here, we describe a step-by-step protocol for density-based separation of urinary EV with high specificity and repeatability. The implementation of integrative omics allows the study of the molecular complexity of highly purified urinary EV, supporting the identification of EV-specific functions and biomarkers. For complete details on the use and execution of this protocol, please refer to Dhondt et al. (2020).
