Oxford University Central Proteomics Facility provides analytical mass spectrometry and proteomics services to UK and international academic medical research labs on not-for-profit basis. We provide quantitative proteomics techniques such as SILAC, iTRAQ and Label free methods in order to study differential protein expression in different cell states eg diseased versus healthy cell. We also routinely provide protein identification using MALDI TOF TOF and LCMSMS electrospray mass spectrometry for SDS PAGE gel bands. We also provide identification of protein post translational modifications such as phosphorylation, methylation, acetylation, ubiquitination etc, etc. Analytical mass spectrometry data is normally provided within two weeks of sample submission.
