The “Molecular Biophysics” facility (french acronym: Plate Forme de Biophysique MoleculaIre, PFBMI) federates an ensemble of state-of-the-art instrumentation for the in vitro molecular-scale characterization of biological macromolecules, together with well established technical and methodological expertise
What do we do ? The mission of the PFBMI is to provide an added value to a great variety of biological projects, enabling the characterization of the intrinsic properties of macromolecules and their assemblies (size, shape, folding, stability auto-association,…) and of the interactions in which they are involved (stoichiometry, thermodynamic and kinetic parameters, …). PFBMI equipments are available for the entire scientific community, in France and abroad, but a priority is given to teams from Institut Pasteur and the Institut Pasteur International Network.
Pricing : services are charged according to the following downloadable chart
Steering committee: Jean-Baptiste CHARBONNIER (CEA Saclay), Alexandre CHENAL (Institut Pasteur), Katherine STOTT (University of Cambridge), Nicolas WOLFF (Institut Pasteur) The PFBMI follows the best practice guidelines of C2RT

In 2008, the PFBMI obtained the IBISA label recognizing it as a French National core facility.
Since 2021, the PFBMI also coordinates the European Horizon 2020 funded project MOSBRI (MOlecular-Scale Biophysics Research Infrastructure), which brings together 13 academic and 2 industrial partners from 11 European countries. MOSBRI provides cutting-edge trans-national access to instrumentation and expertise, carries out ambitious joint research activities and organizes enticing networking activities, such as conferences, training schools and benchmarking actions.
