Proteomics Facility

The Proteomics Facility provides services, self-service equipment, and collaborative research for the detection, characterization, and quantification of biomolecules. The facility labs are located in MBB 1.420 (ICMB) and PHR 1.110 (College of Pharmacy). The facility is supported by the Cancer Prevention Research Institute of Texas Shared Instrumentation Award RP110782 and by institutional funds provided by ICMB, UT-Austin and the College of Pharmacy.

News and Announcements:

The Proteomics Facility will not be running samples or meeting with users from February 10-13 due to a lab wide on-site training. Feb. 5 noon is the deadline for submitting a sample for protein digest before the training, and the next digests will be during the week of Feb. 17. Self-service equipment will be available as usual.

Please visit the Proteomics Facility Wiki at for announcements, protocols and FAQs.

Core Services and Collaborative Projects:

Mass spectrometry:
Protein/peptide molecular weight determination by ESI or MALDI
Protein identification by LC-MS/MS and database search for individual gel bands and complex mixtures
Relative quantitation of peptides/proteins with spectral counting, peak area, or stable isotope labeling by TMT or iTRAQ*
Protein modification analysis for phosphorylation, methylation, acetylation, ubiquitinylation, glycosylation, inhibitor binding, and chemical adduct site determination*

Other MBB lab services/instrumentation:
Edman chemistry N-terminal Sequencing

Self-service instrumentation available:
HPLC and FPLC (4°C or room temperature)
Crystallography robot
MALDI-TOF MS molecular weight determination

When using core services, remember to cite the Proteomics Facility in your publications, and funding sources ES007784 (CRED) and RP110782 (CPRIT) when appropriate, and send the citation to Maria Person. Continued support for the facility depends on documented outcomes.

*If you are interested in collaborating on a protein modification or quantitation project, contact Maria Person.
