exosome isolation

 

qEV provides the most rapid and effective EV/exsosome isolation system available. qEV is based on Size Exclusion Chromatography (SEC), and takes around 15 minutes to get a pure sample of intact exosomes, significantly purer than is possible with concentration methods such as ultracentrifugation (UC) or precipitation reagent kits. 

 

The resulting samples are consistent, standardisable and repeatable, which is required for both research and clinical testing. qEV is now the gold standard for exosome isolation.

With qEV it takes around 15 minutes to get a pure sample of intact exosomes. Reliability has been proven in a large scale inter-laboratory trial.

 

Each column is standardised, quality assured and certified to ISO 13485 standard (Medical Devices) making it perfect for clinical testing. qEV columns provide clean and pure samples without affecting the structure and function of the exosomes.

 
qEV offers fast, gentle & precise isolation exosomes, removing more than 99% of soluble proteins. This makes qEV-isolated EVs/exosomes suitable for electron microscopy, proteomics, RNA analysis, and physical measurement.
