Protocol for isolating plant-derived extracellular vesicles.

PubMed · 2026-02-19

Scientists have developed a reliable, step-by-step method for extracting tiny communication particles — called extracellular vesicles — from plant cells. This standardized protocol makes it easier for researchers worldwide to study how plants send molecular messages to one another.

1

A multi-step purification process — combining four centrifugation and filtration techniques — successfully isolates plant extracellular vesicles from diverse plant species.

2

The protocol effectively removes cellular debris, yielding cleaner vesicle samples suitable for downstream analysis.

3

Isolated vesicles were characterized by morphology, particle size distribution, and zeta potential, confirming their identity and quality.
