Isolation and Profiling of MicroRNA-containing Exosomes from Human Bile

Overview

This protocol outlines a robust method for isolating exosomes from human bile, which can serve as a source of important biomarkers. The isolated exosomes can be used for further analyses, including microRNA profiling, aiding in the understanding of liver diseases.
