Mass Spectrometry and Proteomics Core


The mission of the Proteomics Core at the University of Utah is to provide expert proteomics services and consultation for the University of Utah research communities, as well as to public and private institutions within the state of Utah. The goals of the facility are to provide access to high performance mass spectrometry resources and the latest proteomics technology for researchers in addition to supporting an efficient research and educational environment for sharing ideas, experiences, and knowledge of proteomics. We strive to provide the highest quality mass spectrometry analyses for protein investigations.

The Proteomics Core enables investigators to utilize an array of state-of-the-art mass spectrometry-based techniques for proteomics experiments, ranging from protein identification, post-translational modification characterizations and protein interactions to large-scale quantitative proteomic analyses using data-independent acquisition and tandem mass tag labeling. The staff is available to users for consultation on experimental design and proteomics methods, assisting with data interpretation, manuscript preparation and grant submission.

The primary focus of the Proteomics Core is to support excellent proteomics research in academic, clinical and industry settings. A new project consultation meeting with a proteomics facility core staff member is required for each new project. Please contact the proteomics core facility staff to arrange a consultation meeting prior to sample submission. This core provides and operates as a fee-for-service resource with routine services listed below. Common reagents necessary to perform each proteomics experiment (e.g., reducing and alkylating agents, trypsin, Ziptips, IMAC enrichment kits, tandem mass tags and LC/MS grade solvents) are provided by the Proteomics Core and the costs are already built into the estimated service fee. All project costs will fluctuate based on sample size and experimental design. We will provide a cost estimate following a project consultation with a staff member prior to sample submission.

Instruments

QE-HF Mass Spectrometer

The Q Exactive HF Hybrid Quadrupole-Orbitrap Mass Spectrometer (QE-HF) (ThermoFisher Scientific) is coupled to a Dionex Ultimate3000 RSLCnano System and nano-electrospray ionization for ultimate sensitivity and chromatographic performance. Especially well-suited for proteomics applications, the QE-HF instrument provides high sensitivity (sub-femtomole), high resolution up to 240,000, and high mass accuracy (< 3 ppm), affording greater sequence information and high-confidence protein identifications. The QE-HF is well equipped for protein identification, mapping protein post-translational modifications and protein quantification via tandem-mass tag labeling.

Maxis II ETD

The Maxis II ETD (Bruker) is paired with an Ekspert nanoLC 400 liquid chromatography system and electrospray ionization source. The Maxis is optimal for providing high mass accuracy for intact protein analysis.

timsTOF Pro 2

The timsTOF Pro2 mass spectrometer (Bruker) is coupled to a nanoElute2 nano liquid chromatography system (Bruker) that is advantageous for high throughput label-free quantification of the whole proteome. Trapped ion mobility spectrometry (TIMS) is a gas phase separation technique that resolves sample complexity through an added dimension of separation improving the number of identified peptides in a whole cell or tissue lysate. Time of flight (TOF) is a mass analyzer that uses an electric field to accelerate generated ions through the same electrical potential, and then measures the time each ion takes to reach the detector with high mass accuracy (< 3 ppm) eliciting high confidence peptide identifications.

Charge Rates Procedure / Federal Facilities and Administration (F&A) Rate

Part of the University’s agreement with the Federal Government regarding F&A is that the University will not offer a lower than F&A rate to other kinds of sponsors. That means that the University has to use, at minimum, the same rates for commercial sponsors as it does for the Federal Government. The University would jeopardize its relationship with the Federal Government (the University’s single largest sponsor) if it were to accept rates lower than the current federal F&A rate.

The current F&A Rate is: 54%

The facility internal rate is used when exclusively internal funding sources are used. The F&A / external academic rate applies when external funding sources are used i.e. Federal Government or other academic universities. For more information about F&A rates at the University of Utah please see: 6.3 Indirect Costs/Facilities and Administrative Costs (F&A)
