The Biophysics and Structural Biology (B2S) platform offers a combination of equipment for in vitro physicochemical characterization of proteins and interactions. It provides access to several biophysical (circular dichroism, microcalorimetry, surface plasmon resonance, fluorescence) and structural biology (NMR, X-ray) devices, and is based on the skills of the IMoPA research teams. It belongs to the ARBRE association (Association of Resources for Biophysical Research in Europe) created in 2015. It allows the development of multidisciplinary projects to characterize 1) the interactions involved between biological macromolecules and, 2) the 3D structure biological macromolecules.
The B2S staff has a real technical and methodological expertise to address different issues: The stability / characterization of proteins and complexes in solution, the three-dimensional structure of proteins and complexes, fast kinetics, the characterization of protein-protein and protein-ligand interactions as well as the isolation and characterization of a broad spectrum of products by liquid chromatography.
The platform operates in two modes: 1) the service mode (turnkey services along with, or not, collaborations) and 2) the provision of devices for expert users after initial training.
Any new collaborator must contact the person in charge of the Core Facility to define the best strategy to adopt for the project and complete the service request form. Any user will accept the terms and conditions for service use by signing the agreement form.
We are always available for users during the use of the devices and for any advice and assistance.
Each user must retrieve its data at the end of the analyses. In the usual case, the raw acquisition data are kept for 1 year on computer stations. The platform does not guarantee the recovery of data in case of malfunction. The user is responsible for the final data storage.
