Center for Proteomics and Metabolomics

The interplay of mass spectrometry-based proteomic, metabolomic and lipidomic technologies within the Center for Proteomics and Metabolomics makes it highly adaptable to take on any project.

See Details

OVERVIEW

The mission of the Center for Proteomics and Metabolomics is to provide mass spectrometry-based protein, metabolomic and lipidomic technologies to St. Jude researchers including simple protein characterization, posttranslational modification analysis, comprehensive (phospho)proteome analysis, metabolite and lipid profiling. The interplay of technologies within the same group makes the center highly adaptable to take on any project. Extensive consultation is provided for experimental design, sample preparation, and MS data acquisition and interpretation. The Center has over 2200 square feet of space dedicated for research and instrumentation, and is supported by 13 full time employees.

IMPACT

The Center enables investigators at St Jude to explore all areas of protein and metabolite research.  The Center is constantly evolving and offering new services to adapt to the changing needs of its users.  Because of the extensive research and development activities, including 4 dedicated bioinformaticians building software, there is no need to wait for commercial protocols and solutions to be created. This facilitates access to techniques and data that do not exist elsewhere.

Proteomics has been a really important core for us. They will meet with trainees to make sure the experiments are set up correctly. If there are new techniques that could be used to address the questions, they bring those on. It’s so great to have these resources in house.
