Kinetics – Affinity – Avidity on Cells


SLAS 2023 New Product Award Winner

Characterize molecules binding to membrane targets where they matter: 

on cells.

Biosensor meets cytometry: 
The heliXcyto is the first automated biosensor for Real-Time Interaction Cytometry (RT-IC)

Unique data for membrane targets 

No more mimicking and modeling. Real-Time Interaction Cytometry with the heliXcyto allows you to measure association kinetics, dissociation kinetics, half-life, affinity and avidity directly on cells, preserving the native folding, density, mobility and co-interactions of your molecule of interest by keeping it in its native environment.

Effortless and fast

From cell culture to interaction data in three simple steps with less than 1 h hands-on time thanks to automated workflows.

Compatible with any cell type

We use unique cell traps to physically retain the cells on the chip surface. You can trap any eukaryotic cell type you want within seconds, adherent or suspension, fixed or alive. There is no need for any modifications or specific receptors on the cells’ surface.
