Plateforme de spectrométrie de masse

Spectrométrie de masse

 La plateforme offre une expertise en spectrométrie de masse et peut assister les scientifiques dans leurs analyses protéomiques, qu’il s’agisse de protéines purifiées ou d’échantillons protéiques complexes.

 Nos services vont du simple contrôle de qualité des protéines recombinantes et de l’identification des protéines à la quantification relative des protéomes et à la caractérisation des modifications post-traductionnelles.

La plateforme réalise régulièrement des expériences de quantification sans marquage, mais aussi des analyses de quantification relative après marquage chimique ou métabolique (p. ex. SILAC). Les analyses de données sont effectuées avec les logiciels MaxQuant/Perseus ou ProteomeDiscoverer. Selon la nature de l’analyse, l’échantillon fourni sera sous forme liquide ou dérivé d’un gel SDS-PAGE. Nous pouvons également conseiller et former les chercheurs et les étudiants à la préparation des échantillons et à l’analyse des résultats.

Equipements

 La plateforme est équipée de deux spectromètres de masse : un MALDI-TOF/TOF Axima Performance (Shimadzu) et un système d’électrospray Q-Exactive plus couplé à un système de chromatographie liquide à ultra-haute performance Vanquish Neo nano-flow acquis en 2023 (Thermofisher Scientific), ainsi qu’un système HPLC conventionnel (détecteurs UV et DAD).

Système HPLC permettant une chromatographie préparative et analytique.

Spectromètre de masse en tandem neuf à très haute résolution Q Exactive (Thermoscientific) couplé en amont à une nano-chromatographie liquide à ultra haute performance Nano Easy1000 (Thermoscientific).

Analyses

La plateforme propose différents types d’analyses :

  • Préparation d’échantillon Digestion gel d’électrophorèse (spot ou bande)
  • Digestion en solution
  • Purification de peptides C18
  • Identification de protéines purifiées
    (mélange peptidique simple)
  • Identification de protéines en mélange complexe (séparation chromatographique préalable)
  • Mesure de masse sur protéine entière
    (en solution)
  • Protéomique quantitative : développement de techniques type label free

Des protocoles sont disponibles ci-dessous mais une prise de contact avec le plateau est recommandée avant toute préparation d’échantillon.
Pour toute demande d’analyse contacter : proteomics@ibpc.fr
