Scientific Description
PFBMI, created in 2002 by Dr. Patrick England, is situated at the Institut Pasteur (Paris, France), and is recognized as a National core facility by the French IBISA consortium. It is open to all the scientific community, both academic and industrial, in France and abroad, through a transparent application process. It is the coordinating node of the large European molecular-scale biophysics network ARBRE-MOBIEU (funded by COST from 2016 to 2020). PFBMI federates a state-of-the-art ensemble of 20 instruments for the in vitro molecular-scale characterization of biological macromolecules, together with well-established technical and methodological expertise. The mission of the PFBMI is to provide an added value to a great variety of biological projects, enabling the characterisation 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, …).

Secondary and tertiary structures of macromolecules

Circular dichroism (CD), allows the measurement of secondary and tertiary structures, the analyse of conformational changes, the kinetic of folding and the thermal and chemical stability of folding.Fluorescence spectroscopy give access to the analysis of tertiary conformation, of thermal and chemical stability and of molecular interactions through the measure of fluorescence intensity, anisotropy and life-time. Infrared spectroscopy (FTIR) allows the measurement of secondary structures of macromolecules, specially proteins with high content in ß sheath. https://research.pasteur.fr/en/service/secondary-and-tertiary-structures-of-macromolecules/

Macromolecular architecture, size and shape characterization

Determination of the oligomeric architecture, and of the size and shape of macromolecular assemblies

Thermodynamical stability of macromolecules

Circular dichroism (CD) spectroscopy allows the determination of secondary and tertiary structures, the analysis of conformational changes and the measure of thermal and chemical stability of folding.Differential Scanning Calorimetry (DSC) gives access to the thermal stability of macromolecules and their complexes.
