Facility Details

The Sanford-Burnham Proteomics Facility provides state-of-the-art mass spectrometry-based proteomics services with methods tailored to the needs of scientific investigators for routine mass spectrometric analysis of peptides and proteins, identification of novel proteins, characterization of post-translational modifications, and quantitative proteomics analysis of simple to complex biological samples. The facility identifies, validates and develops new methods designed for the characterization and identification of biologically important proteins. It also supports users with software applications and development, data analysis and experimental design of proteomics studies. The facility is continuously expanding its capabilities in large-scale differential proteomics analysis and phosphoproteomics for unbiased discovery of potential biomarkers and mapping protein profiles. We provide proteomics services to Sanford-Burnham scientists as well as outside non-profit and for-profits organization on a fee-for-service basis.
