Abstract
Investigations into the biological role and composition of bacterial extracellular vesicles have grown in popularity in recent years. Vesicles perform a variety of functions during interactions with eukaryotic host cells, ranging from antibiotic resistance to immune modulation. It is necessary to isolate vesicles in order to understand their biological functions. Here we describe a polymer-based precipitation method allowing high-yield isolation of extracellular vesicles and their cargo RNA from the Gram-positive bacterium Staphylococcus aureus.
