The aim of the UTMB Mass Spectrometry Facility is to assemble state-of-the-art instrumentation, highly skilled technical staff and methodology to provide experimental capabilities required to support faculty driven research programs. 

Orbitrap FusionThe Mass Spectrometry Facility serves as the hub of the UT-System Proteomics Network and is well-equipped with a suite of LC-MS systems including the ThermoScientific Fusion Orbitrap MS, the Sciex 5600 TripleTof, 6500 Qtrap, and 5800 Maldi TofTof.

The core provides a range of services, including:

  • Intact molecular weight measurement
  • Protein identification from gel bands
  • Protein identification from complex mixtures
  • Identification of post-translational modifications
  • SILAC, iTRAQ, and label-free quantification of peptides and proteins
  • Small molecule quantification
  • Metabolomics
