Presentation

Currently, the NMR facility operates 6 high-field NMR instruments at magnetic field strengths ranging from 600 MHz to 950 MHz, equipped with state-of-the-art liquid state (cryogenic probes, sample changers), and solid state (high-speed MAS probes) capabilities.

NMR access methods

The NMR facility provides access to national users since 1997, and is part of the French high field infrastructure Infranalytics (FR 3050). At the European level, the NMR facility of IBS (with its regional NMR partner in Lyon) has taken part in several successive European access programs: FP6-I3-EU-NMR (2006-2010), FP7-I3-BIO-NMR (2010-2014), H2020-I3-iNEXT (2015-2019), and H2020-I3-iNEXT-DISCOVERY (2020-2024). Access can also be obtained via INSTRUCT-ERIC. The NMR facility provides access to NMR instruments, as well as the expertise needed for NMR data acquisition and processing.

We also offer a protein quality controll service (purity, oligomerization state, structure degree). For more details, see
1D Quality Control Platform

Preparation of isotope-labeled NMR samples (2H, 13C, 15N)

We also offer limited user access to our facility for large-scale expression of isotope-labeled proteins in E.coli, under the supervision of a trained platform engineer. Dedicated benches, optimized protocols and appropriate isotope-labeled chemicals are available for the following services:

  • Protocols and technical advice for large-scale production of uniformly 13C, 15N-labeled proteins.
  • Feasibility studies and training for large-scale production of protein overexpression in perdeuterated media.
  • Large scale overexpression of [15N, 13C and 2H] labeled proteins and [13C1H3]-methyl specifically labeled proteins.
    in a highly (>98%) perdeuterated medium.

ISO 9001

The high-field NMR and isotope labeling platforms obtained ISO 9001/v2008 quality management certification in July 2011, an essential label and guarantee of quality for all platform users.
