Activities
PRISMM (Research and Innovation Platform in Mass Spectrometry and Metabolomics) is a platform with a vocation for service provision, research and training, focusing essentially on the identification and the quantification of new biomarkers. As such, it proposes the analysis and assay of small molecules of a molecular weight inferior to 2000 Da, from samples of extremely different natures, via innovative analysis methods coupled or not with mass spectrometry. The platform’s expertise applies to the identification, analysis and assay of small molecules via UHPLC-MS/MS, UHPLC-UV, HPLC-UV coupling
The platform’s skills reside in particular in the preparation of complex samples through solid phase, liquid/liquid, and imprinted polymer extraction. Small quantities of relevant compounds can also be purified from a complex mix. The command of extraction techniques enables biomarker analysis in all types of matrices, whether associated with health issues (serum, red blood cells, whole blood, urine, brain, cerebrospinal fluid, etc.), or with the environment (water, sediments, fish, molluscs, cephalopods, etc.). Large series can be analysed. PRISMM boasts nationally and internationally renowned know-how, in particular in the analysis of DNA bases modified by exposure to genotoxic compounds (DNA adducts), but also in the analysis of neurotransmitters and their metabolites.
Analysis can be conducted in the form of simple service provision, extended services including perfecting and validation of new analysis methods or in the form of research partnerships.
