Aislamiento y purificación de vesículas extracelulares bacterianas a partir de heces humanas mediante centrifugación en gradiente de densidad

Overview

This study presents a protocol for isolating and purifying bacterial extracellular vesicles (BEVs) from human feces using density gradient centrifugation (DGC). The method reduces centrifugation time significantly and enhances BEV separation from contaminants, providing a standard approach for future research on BEVs.

Key Study Components
