La plateforme MetaToul-Agromix peut être sollicitée par la communauté scientifique publique et privée pour des analyses qualitatives et quantitatives de métabolites végétaux et microbiens pour :

• Réaliser des prestations de service pour répondre à des besoins ponctuels
• Développer de nouvelles méthodes. Une collaboration ou un partenariat peut être élaboré dans le cadre du montage et de la mise en œuvre de projets de recherche.
• Mettre à disposition des instruments analytiques.

Activités de Recherche et Développement

Métabolomique Globale :

Déréplication d’un extrait complexe

Analyses multivariées (classification, régressions, analyses discriminantes)

 Approches multi-omiques

 Métabolomique Ciblée : 

Métabolites végétaux : phytoalexines, d’alcaloïdes, composés phénoliques, flavonoïdes, …

Métabolites microbiens : lipochitooligosaccharides (LCOs), chitooligosaccharides (COS) …

Une collaboration ou un partenariat peuvent être élaborés dans le cadre de la mise en œuvre de projets de recherche.
