Platform for metabolic analyses provides the services for the metabolic measurements in vitro and in vivo. The aim is to integrate metabolic studies in fundamental research projects to assess cellular and organism physiology. Our project stems from the need to share the equipment and expertise of the labs at Paris Descartes University, Imagine and INEM Institutes by creating a common facility and research network. An important goal is to acquire state-of-the-art equipment.



Metabolic platform can help to assess metabolism on different levels:

Référent scientifique  

XFe 96 Extracellular Flux Analyzer can simultaneously interrogate the two major energy producing pathways of the cell – mitochondrial respiration and glycolysis - in a microplate format, in real-time.


Q Exactive Plus benchtop Orbitrap mass spectrometer, equipped with an Ion Max source and a HESI II probe (Thermo Scientific). This system is capable of measuring mass-to-charge ratios with less than 5 ppm error and a resolution of up to 140,000 and can also collect MS/MS fragmentation data. Mass spectrometer is coupled to a Dionex UltiMate 3000 ultra-high performance liquid chromatography (UPLC).

XFe 96 Extracellular Flux Analyzer - Seahorse

To use the Seahorse machine please contact the platform to arrange the meeting for discussion of the experimental strategy. Certain cell types will requier the initial tests for an assay optimisation (cell type, cell number, concentrations of the inhibitors). Users can be trained to perform measurements in autonomous mode.



Measurements of Mitochondrial respiration (basal, maximal (FCCP treatment) and spare respiratory capacity (Rotenone and Antimycin A treatment), Glycolytic function (glycolysis, glycolytic capacity (Oligomycin treatment), glycolytic reserve (2 Deoxy-D-glucose treatment) or Fatty acid oxidation
