Biophysics and biomolecular screening

This multidisciplinary platform allows the identification and validation of therapeutic targets and molecules specifically targeting these biological targets. In particular, this platform allows (i) chemical and functional screening using different biological and cellular assays as well as (ii) the complete characterization of interactions (affinity, binding mechanisms, structure) between biomolecules by different biophysical approaches. A peptide synthesis service is also offered.
