qEV ISOLATION PLATFORM

Higher-Purity Extracellular Vesicle Isolation. Built to Scale.

The qEV Isolation platform sets the standard for EV purification – now extended to LNPs and beyond, with the precision, scalability and bioprocessing expertise your application demands.

Unmatched separation

Our exclusive resin and carefully optimised qEV columns deliver highly pure isolates.

Quality that scales

Process 150 µL through to thousands of litres, with a level of quality that is maintained with increased throughput.

Backed by deep expertise

Draw on 30+ years of bioprocessing experience to fast-track your isolation workflow development.

Gentle, Size-Based Separation – Built for EVs

qEV columns isolate extracellular vesicles by size exclusion chromatography (SEC). As your sample flows through the porous resin, larger particles like EVs pass around the beads and elute first, while proteins detour through the small resin pores and trail behind.

Particles stay intact, as separation is achieved gently under gravity, without high centrifugal or shear forces.

From EVs and exosomes to LNPs, the qEV platform supports a range of particle sizes and sample volumes.

More Than Your Average SEC Column

The exclusive Gen 2 resin used in qEV columns has been optimised for superior EV-protein separation and maximal purity. Alongside that, column manufacturing has been refined for greater consistency and quality. That translates to:

  • Unmatched plasma EV purification
  • Purified isolates derived from cell culture media, milk, CSF, urine and more
  • Removal of unbound labels and other impurities, alongside significant lipoprotein removal
  • cGMP-ready columns available on request

Fast-Track Development With Expert Support at Every Stage

We've done the groundwork, so you don't have to. Our isolation refinement expertise – including single-particle measurement capabilities for assessing elution profiles – gives your workflow development a major headstart.

As your needs evolve, our bioprocessing team is ready to support you, whether through customised GMP-ready solutions, pilot studies for refining SEC-TFF workflows, or beyond.

Laboratory fluid control system with touchscreen interface, tubing, and a bottle on a digital scale labeled Mass 2.

No Sample Left Behind

Science doesn't come in one size. Neither do our columns.

Whether you're working with precious microlitres or running industrial scale pilot studies, our qEV column range has you covered. From 150 µL to 100 mL and well into industrial scale, there's a column for every challenge.

Stated sample loading is the recommended volume for highest purity. All columns are reusable up to five times.

A Workflow for Every Application

General Research

Work with the purest EVs possible as you unravel their fate, function, and uptake, and explore strategies for clinical applications. The qEV Isolation platform delivers the reproducibility your research demands, from first isolation to final publication.

EV Diagnostics

Advance towards clinical validation without building a scaled workflow from scratch. Robotic liquid handling, bulk order discounts, cGMP-ready columns, and ISO 13485:2016 certification mean you can focus on the science, not the logistics.

Bioprocessing

Scale EV therapeutic and LNP production with confidence — from pilot study to cGMP-ready manufacturing. With custom column builds, automation, tangential flow filtration and 30+ years of bioprocessing expertise, the qEV Isolation platform is built for the full bioprocessing journey.

In Our Customers' Words

“We required a concentrated, high-quality EV isolate for our
in vivo animal studies, which we believe could be the foundation for future human translational work. The team optimized the process and purified the sample we provided, enabling us to proceed quickly to the next phase of our research. We are excited and look forward to leveraging Izon’s expertise to scale up the process for future clinical studies. Their collaborative support throughout this project has been invaluable, and I cannot thank them enough.”

Professor Shilpa Buch, PhD

University of Nebraska Medical Center

"Izon’s qEV columns offer a simple, effective and reproducible way of purifying EVs directly from biofluids or from EV enriched samples following differential centrifugation. During my PhD at Queensland University of Technology we used qEVoriginal columns (70 nm) for all of our EV preps from plasma and milk samples, prior to mass spectrometry-based proteomics and microRNA sequencing. Our group produced over 10 publications using these columns and continues to be satisfied with the results. I would highly recommend incorporating qEV columns as part of the EV enrichment workflow for any researchers struggling with EV yield and purity."

Resources

How much does EV isolation process development and sample processing cost?

To give you an idea, you can outsource your EV isolation scale-up of ~6-10 L batches for a very competitive cost of ~25K USD. To discuss the cost of tech transfer and for other volume ranges, talk to the team.

Where can samples be processed?

Currently, this service is run from our facilities in Boston and in Lyon. If you are based outside the US or Europe, let us know your requirements to see what we can do.

What sample volumes do you work with?

In addition to being the leading provider of EV isolation solutions for sample volumes from 150 µL to 100 mL, we have recently processed samples for customers ranging from 1 to 2000 L starting volumes! For those scaling in volume, we have found that the 6-10 L range serves as a practical volume for feasibility studies, where it makes sense to optimise around this range before going much larger.

What sample types do you work with?

The principles of sample preparation and isolation remain the same for most sample types. Therefore, we are open to whatever project you have in mind – just reach out to the team to confirm it will be a good fit.
