Core Facilities

Proteomics/Mass Spectrometry

Jun Qu, PhD, with the mass spectrometer.


We focus on:

  • ultra-sensitive quantification of small-molecule analytes such as drugs, metabolites and biomolecules
  • comprehensive protein expression profiling and differential proteome analysis
  • ultra-sensitive quantification of proteins/peptides


  • ThermoFisher Orbitrap Fusion Tribrid with ETD (Electron Transfer Dissociation) fragmentation
  • ThermoFisher Quantum Ultra EMR triple quadrupole mass spectrometer
  • Eksigent multidimensional nanoflow HPLC system
  • Waters Acquity Ultra-high pressure (UHPLC) chromatography system

Our instruments are available on a limited basis to UB and Western New York researchers.
