Mass Spectrometry/Proteomics

The Proteomics division of the Laboratory for Molecular Biology and Cytometry Research is committed to providing the highest quality services related to proteomic analysis, specifically biomolecule mass spectrometry. The instrumentation available for mass spectrometry services includes an ABSciex QSTAR Elite hybrid quadrupole/TOF mass spectrometer, a Bruker Daltonics – Ultraflex-2 MALDI-TOF, and a Waters Synapt G2-S High Definition mass spectrometers. Several of our mass spectrometers are coupled to HPLC instruments which allows us to provide additional applications to our researchers.  The QStar is paired to 1D LC systems (Michrom Paradigm) while the Waters Synapt is paired to a 2D UPLC (nanoAcquity) in order to allow processing of more complex proteomic type samples.

If you have any additional questions, please email the lab group (Lmbcr_help@ouhsc.edu) or contact Dr. Virginie Sjoelund.

To speak with someone in person, please feel free to call the main facility number at (405) 271-2337 to schedule an appointment during normal operating hours.

Our Office Hours are Monday through Friday: 8:00am to 5:00pm.

Sample Drop Off is available Monday through Friday: 8:30am to 4:30pm.

Note: All samples dropped off for proteomic analysis or for protein identification on a Friday won't be processed until Monday.

Turn around time: It takes about two weeks to get the samples processed and analyzed.
