Laboratory of Biomolecules Structure and Function

"Development and application of techniques for the structural description of clinical-relevant biomacromolecules and the understanding of their structure-function modulation."


We offer our expertise, as well as consultancy or collaboration within a diverse range of issues broadly defined as protein biochemistry and biotechnology, protein structure solution or prediction, mass spectrometry and biomacromolecule analyses,

particularly in the fields of:

- Recombinant protein expression and purification (both in bacterial and in mammalian cell line expression systems)

- Protein characterization and binding assessment (by various biochemical and biophysical techniques, e.g. sedimentation analysis in analytical ultracentrifuge, surface plasmon resonance, UV-VIS & CD spectroscopy)

- Protein structure determination (by protein X-ray crystallography or by advanced techniques of mass spectrometry)

- Multi-protein dynamics mapping

- Molecular dynamic and protein structure modelling
