The NICB is equipped with a state-of-the-art proteomics and mass spectrometry core facility, which is supporting many research programmes in the NICB and DCU, as well as providing proteomic input to several external academic, clinical and industrial collaborators.

The facility is equipped with proteomic infrastructure for:

  • Protein/peptide separation
  • Protein/peptide identification (gel and gel-free)
  • Protein/peptide characterisation (e.g. post-translational modifications)
  • Quantitative differential protein expression analysis with labels (e.g. TMT) and without labels (e.g. label-free LC-MS)
  • Targeted proteomics.

The proteomic equipment includes:

  • Orbitrap Fusion Tribrid with ETD mass spectrometer (funded through an SFI Infrastructure Award to DCU)
  • LTQ Orbitrap XL mass spectrometer
  • LTQ-XL mass spectrometer
  • TSQ Vantage Triple Quadrupole mass spectrometer
  • Ultimate 3000 RSLCnano LC systems.

Associated analysis software includes:

  • Progenesis QI for Proteomics
  • ProteomeDiscoverer – using MASCOT and SEQUEST HT
  • Biopharma Finder.
