CF Proteomics

The facility provides a complete platform for the identification and quantification of proteins using mass spectrometry. We are equipped with state-of-the-art chromatography systems and mass spectrometers that enable multiple MS and LC-MS/MS experiments:

  • Orbitrap Fusion Lumos Tribrid mass spectrometer (high resolution ESI mass spectrometer) coupled to nanoAcquity UPLC
  • LTQ Orbitrap XL ETD (high resolution ESI mass spectrometer) coupled to 2D nanoHPLC
  • LTQ (low resolution ESI mass spectrometer) coupled to GE MDLC
  • UltraflexII tof/tof (MALDI mass spectrometer)
  • Procise 494 (Edman sequencer)
  • 1260 Infinity (HPLC)
  • Easy nanoLC coupled to fraction collector/MALDI spotter (nanoscale preparations)
  • Sample preparation robot (in-gel digestion of large sample sets)

In addition, the facility provides a wide-range of software and bioinformatics tools for data analysis and interpretation:

  • Mascot Server
  • Proteome Discoverer
  • MaxQuant
  • Scaffold
  • Multiple in house written procedures based on R\Bioconductor
