Whole Blood Opens New Route to Biomarker Discovery

A rapid enrichment method could unlock archived blood samples for extracellular vesicle–based diagnostic research

Share

1

A new method for extracting extracellular vesicles (EVs) from whole blood could enhance diagnostic biomarker discovery.
2

The optimized PROSPR workflow produces purified EVs suitable for protein and lipid analysis in under 20 minutes.
3

Whole-blood EVs contain unique molecular information not captured by plasma EVs, including 251 distinct proteins.
4

The study highlights the potential of using stored whole-blood specimens for revisiting existing cohorts in EV research.
