Software Systems

• The role of the Metabolomics & MS Core is to provide instrumentation and analytical expertise to the Vanderbilt research community via an open-access instrument facility.

• The facility is used each year by about 175 investigators each year in 75 research groups at the University. Overall core instrument use is about 11,000 - 12,000

instrument-hours/year.

• The facility is operated as an open-access facility in which users are expected toprepare samples in their labs, then bring them to the Core for analysis.

• In order to facilitate research training, the Core sponsors an active MS training program to teach new users how to design experiments, do the sample

preparation,operate the instrument and interpret the results.

• Core personnel assist users with development of analytical methods when that is the most expedient approach to solving a tough analytical problem.

Tissue Imaging and Biofluids Core Personnel

L to R: Julie Coleman, Michele Reyzer,PhD;, Olivia Faison, Erin Seeley,PhD, and Lisa Zimmerman, PhD.

The Tissue/Biofluids Core Facility provides:

Direct proteome profiling and protein imaging of intact tissue by MALDI-MS.

Tissue Profiling typically involves many samples of several types, and the goal is often to discover patterns in the protein profiles of the samples that can classify the samples based on biological state. (e.g., tumor vs. normal) and that can predict biological outcomes (e.g., the prognosis of a patient).

Tissue Imaging is usually performed on a small number of samples where the goal is to obtain a relatively high resolution image showing the distribution of various proteins in the tissue section.

Proteome profiling of serum, plasma and other biofluids by MALDI-MSgenerates spectral patterns in the protein profiles as a tool used to differentiate between disease states.

Multidimensional Analysis (LC-MS-MS) of Biofluids comprehensive analysis of fluids providing inventory of protein identified in samples.

m/z 10,165 m/z 12,135

MS images of mouse kidneys infected with S. aureus. The signal at m/z 10,165, tentatively identified as calgranulin A, is present in the kidney abscesses, but is absent in healthy tissue. The signal at m/z 12,135 appears down-regulated in infected tissue and is absent in abscessed tissue.
