The LRSV hosts the MetaToul-AgromiX platform. This platform is dedicated to the analysis of plant metabolites as well as fungal and bacterial metabolites that may be involved in biotic interactions.

The MetaToul-AgromiX platform is part of the Metabolomics and Fluxomics platform in Toulouse (MetaToul), technological platform of the GenoToul.

It brings together scientific and technical skills (researchers, engineers, technicians) and resources (advanced equipments: Nuclear Magnetic Resonance, Mass Spectrometry, Sample Preparation Robots) in the field of global metabolism analysis.
MetaToul provides the scientific community with concepts, tools and methods related to the analysis of metabolism in cells, tissues and organisms.

The MetaToul platform, certified IBISA, is committed to a quality approach which is an essential tool for the continuous improvement of its operation and thus the quality of the services of the platform.
It is ISO 9001 and NFX-50-900 certified.

MetaToul is a partner of the MetaboHUB National Metabolomics and Fluxomics Infrastructure project led by Fabien Jourdan, with the Bordeaux, Clermont-Ferrand and Saclay platforms.

How to make a project request

 An access mode has been defined by the MetaToul platform according to the following schema:

  

  1. The applicant contacts the MetaToul platform using the MetaboHub project request site (MAMA):

https://mama-webapp.metabohub.fr/

  1. The tray manager will contact you to discuss the project in order to evaluate, accept or reject it.

The project may eventually be returned to another platform of the MetaToul platform or another platform of the MetaboHUB infrastructure.

When the project is accepted, a project manager is appointed.

  1. A “study and service proposal” will be sent to you by the project manager. It contains the conditions and commitments, the terms of implementation, the deadlines and the price.

4. The applicant then returns the signed proposal to the project manager to begin the project.
