Background:

Extracellular vesicles (EVs) are crucial for intercellular communication, carrying biomolecules between cells.
Current methods for EV concentration face challenges like time consumption, high cost, and sample contamination.
Lack of standardized EV concentration methods hinders research reproducibility and functional studies.

Purpose of the Study:

To address the need for accessible and sustainable methods for EV concentration.
To present a novel combined approach for improved EV isolation.
To enhance the yield and purity of EVs for downstream applications.

Main Methods:

A novel combination of three established methods was employed for EV concentration.
The protocol aims to overcome limitations of traditional and commercial EV isolation kits.
Focus on achieving moderate-to-high EV yields with reduced protein contamination.

Main Results:

The combined method yields moderate-to-high concentrations of EVs.
Significant reduction in protein contamination compared to conventional techniques.
The protocol is designed to be accessible and sustainable for researchers.

Conclusions:

The novel combined method offers an improved approach for EV concentration.
This technique facilitates more reliable in vitro and in vivo functional studies.
Enhanced EV isolation is critical for advancing EVs-related research.
