- iNEXT offers access through three different access themes and specific modalities through a peer-reviewed process (at the bottom of the page is a table with reviewers).
- The submission of iNEXT proposals requires all people involved to be registered with Instruct.
- PLEASE NOTICE: there may be a waiting list for certain popular modalities!
- Scientific Excellence of the proposed research theme

1. Structural Audit
Mail-in services for basic sample analysis; does not include a visit and the analysis is done by local experts.
2. Enhanced Support
The modalities here include structure solution by X-ray crystallography, SAXS or NMR, EM sample optimisation, ligand and fragment screening, and the study of macromolecular interactions in vitro or ex vivo (in cells). This type of access is guided by experts in the host institutes and involves training and active participation of visiting users.
3. High-End Data Collection (experts)
Expert users can use some of the best synchrotron beamlines, high frequency NMR magnets and state-of-the-art cryo-EM instruments.
Description of Available Modalities
A macromolecular sample is sent to iNEXT and assessed for suitability for structural studies. Sample quality, quantity, stability, crystallization potential is evaluated and a preliminary characterization by SAXS is performed. If the sample is suitable for NMR studies (Mw < 40 kDa) or for EM studies (Mw > 200 kDa), the user can request a pre-analysis for NMR or EM studies. Results will be combined in a Structural Audit Report.
Cryo-EM sample optimisation
We will help you to move your project from negative stain images to cryo-EM grids ready for high resolution data collection.
Accessing to expertise and biophysical equipment to quantify macromolecular interactions. We will help you design, perform and analyse your experiments, and provide 1-2 weeks access to our equipment, including surface plasmon resonance, multi-modal fluorescence plate readers, isothermal titration calorimetry, microscale thermophoresis, stopped flow equipment, multi-angle laser light scattering, and label-free thermal shift assess.
Following the success of Biostruct-X and its predecessors, this mode aims to provide access to expert synchrotron users. Note: although “BAG”s are available, these will now have to be grouped under a common and coherent research theme for each new BAG.
Following the success of BioNMR and its predecessors, this mode aims to provide access to expert NMR users.
For the first time, transnational access to some of the best electron microscopes in Europe for single particle cryo-EM, CLEM, and other experiments.
Peer Review and Expected Access Timeline
Proposals can be submitted at any time and are reviewed by a panel of experts that are not associated with the research infrastructures. Proposals are assessed for their scientific merit, but also their value for translational research, their technical feasibility and the quality of the team. The detailed score criteria are:
It is important to know that a proposal failing any one of the listed criteria (achieving a red score) will be rejected. In addition, it will be necessary to achieve a score of at least 10 to qualify for approval. Some access modules that are highly popular will naturally need higher scores to achieve high ranking, while for other cases achieving a qualifying score will be enough. Adjustment to these will be made according to available budgets are perceived popularity by the users.
We aim for rapid turnaround of proposals (less than two weeks). Some of the more complicated proposals (especially in the Enhanced Support access theme) are pooled and ranked periodically. Following approval, experiments are scheduled by the facilities.
