The group « Neuroproteomics and Biomarkers » (C. Hirtz) aims to exploit the latest technological developments in proteomics for the discovery, validation and use of clinical biomarkers (proteins, PTMs, ARN, ADN, metabolites) in neurodegeneratives diseases.

Our team is contituted of 4 development engineer (Dr. J. Vialaret, E. Attina, L. Fichter et L. Tiers), 2 clinical technician (J. Kindermanns, N. Ginestet), 7 researchers (Pr. S. Lehmann, Pr. C. Hirtz, Dr.  C. Delaby, Dr. X. Ayrignac, Dr. E. Moulis, Pr. P Labauge et Pr. D. Deville de Périère) and 5 PhD (P. Mohaupt, S. Coppens, ML. Pons, A. Amalric, S. Muccio).



Our research are highly supported by a strong methodological development activities mainly dealing with prefractionation, preanalytical, innovative mass spectrometry approaches and clinical proteomics expertise.

To reach our goals, several high throughput technologies are available (targeted mass spectrometry, biomarkers discovery in complex matrices, ultra-sensitive and multiplexed immunoassays). For that purpose, we are currently equipped with last generation LC-MS/MS mass spectrometers (Q-TOF Impact 2 Bruker Daltonics et 3xTQ 8060 Shimadzu), a Maldi TOF (Axima Shimadzu), a high throughput sample preparation and fractionation robot (Bravo Assay Map Agilent) and ultra-sensitive and multiplexed immunoassays (SIMOA Quanterix HDX et Quickplex 120 MesoScale Discovery).
