Abstrakt: Urinary extracellular vesicles (uEVs) are a promising substrate for discovering new biomarkers. In order to investigate the origin of uEVs and the cargo they carry, some types of downstream analysis of uEVs may require concentration and enrichment as well as removal of contaminating substances. Co‐isolation of the abundant urinary protein uromodulin with uEVs can be a problem, and may interfere with some techniques, in particular with proteomic analysis tools. Methods of separating out uromodulin and its removal have also not been standardized. This review highlights aspects of uromodulin structure that makes it recalcitrant to separation from uEVs, summarizes frequently used techniques for uEV enrichment and how they affect uromodulin separation, and specific methods for uromodulin removal during preparation of uEVs. The necessity of uromodulin removal for various study endpoints is also examined. [ABSTRACT FROM AUTHOR]
