Only EVs respond to the dielectric field

Proteins and lipoproteins can overlap EVs in size, but because their structures differ, they don’t polarize the way EVs do when dielectrophoresis (DEP) is applied. We leverage these differences to selectively capture EVs. The result is gentle isolation of EVs ready for your downstream analysis.

Walk-away while Demeter EVPrep does the work

Demeter EVPrep automatically polarizes, captures, washes, and elutes your EVs, all within the cartridge. Your gently isolated EVs are label-free and ready for your discoveries.

1 ·

Polarize

A non-uniform AC field induces a dipole moment selectively in EVs.

2 ·

Capture & Wash

EVs are pulled to the electrode edges and washed while similarly sized proteins pass through in the flow.

3 ·

Elute

Field off — EVs release into a small volume, concentrated and label-free.
