The University of Texas at San Antonio (UTSA) Proteomics Core is focused on capillary liquid chromatography-mass spectrometry (LC/MS) and -tandem mass spectrometry (LC/MS/MS), to identify, characterize, and quantify proteins. We are funded by a Research Centers in Minority Institutions (RCMI) grant from the National Center for Research Resources (NCRR) at the National Institutes of Health (NIH), UTSA, and generous donations.
