Protein Structure & Biophysics

Solve and Understand your Protein-Ligand Interactions

The Protein Structure & Biophysics (PSB) platform specializes in the determination of high-resolution structures of proteins and protein-ligand complexes. In the context of drug development, understanding protein-ligand interactions is pivotal for accelerating lead identification and structure guided lead optimisation.

The PSB team provides solutions tailored to your needs starting from construct design, protein expression & purification, screening for crystal hit identification & optimisation of crystallisation conditions to atomic structure solution. The PSB team has access to both in-house diffractometers and commercial beamline at synchrotrons to provide fast turnaround to your projects. Experienced crystallographers with expertise on various target proteins will work together with the clients.
