Application Areas


Drug Development for Biologics and Small Molecules

Fresh information, earlier in the pipeline switchSENSE® identifies and thoroughly characterizes potential hits through advanced kinetics and biophysical characterization of size, shape and conformation.


Quality Control in Production Process Monitoring

Characterizing enzyme activity and reproducible lot-by-lot quality measurements, switchSENSE® offers a brand new tool – extremely rapid, highly insightful, radiation free.


Biophysical Analysis in Life Science Research

In tandem with our high specificity kinetic measurements, switchSENSE® uses molecular rulers and the measurement of molecular dynamics to give real time mapping of size, conformation, shape and position of interacting partners.

In Focus

Paper in Nature Communication 2017 I Specialized interfaces of Smc5/6 control hinge stability and DNA association

We are very excited about the outcome of our cooperation with Antony W. Oliver from the University of Sussex.

Cohesin, condensin and Smc5/6 belong to the group of Structural Maintenance of Chromosomes (SMC) complexes which are involved in the organization of higher-order chromosome structure. The paper exhibits that the Smc5/6-hinge, like those of cohesin and condensin, also forms a toroidal structure, however, with an unusual ‘molecular latch’ and a functional ‘hub’. Defined mutations in these interfaces cause severe phenotypic effects with sensitivity to DNA-damaging agents in fission yeast and reduced viability in human cells. By the switchSENSE® technology it was shown that WT Smc5/6-hinge readily associated with and dissociated from immobilized ssDNA. This interaction is affected by both ‘latch’ and ‘hub’ mutations, suggesting a key role for these unique features in controlling DNA association by the Smc5/6 complex.
