Get the right results, right on time with KEI

Before After

Established in The Netherlands in 2011, Kinetic Evaluation Instruments BV (KEI) designs and manufactures Surface Plasmon Resonance (SPR) instruments, bioanalytical sensors and SPR-specific software for a variety of research applications.

The KEI SPR help scientists analyze bi-molecular interactions in real time, without any labelling requirements. The study and characterization of molecular interactions are essential to explore the natural relationships of biomolecules to help scientists understand biological ecosystems on a molecular level.

SPR has become a standard tool in both industry and academia and is widely accepted and used in life science and pharmaceutical science laboratories across the globe. KEI SPR brings valuable benefits to a range of applications, involving interactions between all classes of biomolecules: proteins, peptides, DNA and RNA, lipids, carbohydrates as well as small molecules, cells and even bacteria.

The KEI SPR instruments distinguish themselves by unconventional design, high performance and accuracy for a low total cost of ownership.
