Purify Particles at Scale with qEV Isolation

Pure & gentle

Purify intact particles efficiently without subjecting them to high forces.

Scalable

A standardisable isolation method that can be adapted to your current stage and grows with your progress.

Versatile

Purify particles for fundamental research through to diagnostic development and therapeutic production.

Isolates graph

Elution profiles of qEVoriginal columns from different series with 0.5 mL of human plasma loaded. Particle concentration (mean ± standard error) was measured using the Exoid, and protein concentration (mean) was measured using a bicinchoninic acid assay. n=3 for each column series. BV = Buffer Volume; Default PCV = Default Purified Collection Volume.

Collect Highly Purified
Isolates with SEC

Harness size exclusion chromatography (SEC) to gently separate particles of interest from contaminants. qEV columns are supported by automation and optimised to maximise particle purification from a wide range of sample types and volumes.

In-house studies show qEV columns remove ~99% of contaminating protein and >99.99% of ApoA1 from human plasma, with an impressive ~99% of ApoB removed by qEV columns from the 70 nm series.

Scale Isolation as Your
Operation Grows

We are here to make sure your isolation methodology and technology scales with you as your project evolves.

Our growing range of automated qEV instruments ensure you slash manual labour and implement standardisation right from the start, while our isolation processing team is here to support you as your operation expands.

Superior Purification at Any Scale

In addition to their added convenience, speed and scalability, qEV columns offer superior purity over other isolation methods.

While qEV columns from the 70 nm series excel in this department, isolates from the 35 nm series are also significantly purer than ultracentrifugation and precipitation methods.

Meanwhile, qEV columns from the 20 nm series sacrifice purity for improved particle recovery, and improved isolation of smaller particles.

Choose Your qEV Series

All qEV column sizes come in three different types, referred to as qEV series. These series are distinguished by the pore size of the resin used – 20 nm, 35 nm, and 70 nm – and each produces isolates with distinct characteristics.

20 nm series

When more is more: maximise particle recovery

Obtain a higher number of smaller particles,  including EV-sized particles and smaller.

With more small particles captured, EV isolate purity is inherently lower.

35 nm series

The middle ground: when particle recovery and purity are of similar importance

Compared to the 20 nm series, protein removal is superior.

EV isolates are not as pure as with the 70 nm series.

70 nm series

When less is more: maximise EV isolate purity

Get purer EVs, at the cost of a slightly lower yield than that of the other qEV series.

By far the best at separating EVs from lipoprotein and other protein contaminants.
