6 ways K-One enhances SPR analysesand simplifies your workflow (your life?)

1

Complex systems

We enable even the most challenging SPR assays by customizing sensors and applying our K-One® chemistry to fit your applications, molecules, and instruments.

2

Non-specific biding reduction

With K-One®, the chip surface is flawlessly protected, ensuring minimal background noise and delivering consistently clean, reliable sensorgrams, even in complex samples.

3

Robust sensor-chips

Ligands remain firmly attached while maintaining full activity on the surface, enabling repeated injection and regeneration cycles even for challenging interactions — ensuring robust and reproducible assays.

4

Density control

Our ability to adjust ligand density and control its homogeneous surface distribution allows us to work under affinity conditions by minimizing avidity effects and avoiding recapture. We can also work under avidity conditions when the project requires it.

5

Complex samples

K-One delivers consistent and reliable results across a wide range of complex biological matrices, including plasma, serum, and hybridoma/stem cell supernatants. Our surface chemistry enables direct ligand immobilization without intermediates, or integrates seamlessly with capture systems like steptavidin, protein A/G, anti-FC and anti-Fab.

6

Broad compatibility

Our K-One chips work with any gold-based biosensing platform, including Cytiva SPR, Horiba SPRi, Carterra HT-SPR and others. K-One surface chemistry enables direct ligand immobilization without intermediates and can integrate seamlessly with capture systems like streptavidin, protein A/G, anti-FC and anti-Fab.
