Proteomics

The PFGRC Proteomics Facility couples sophisticated protein separation technologies with electrospray and MALDI mass spectrometry to conduct research studies and develop publicly available data sets focused on microbial agents of infectious disease and biodefense. Studies conducted thus far have included a comparative protein abundance analysis of three isogenic Staphylococcus aureus strains derived from a clinical vancomcyin-intermediate S. aureus (VISA) isolate (in collaboration with Emmanuel Mongodin, the J. Craig Venter Institute and Steve Gill, SUNY, Buffalo), the characterization of the periplasmic subcellular proteome of the Yersinia pestis strain KIM6+ in defined medium in vitro and in response to temperature shifts (26°C and 37°C) (in collaboration with Robert Perry, University of Kentucky), and a comparison of in vitro and in vivo proteome profiles, including membrane associated proteins of the enteropathogenic bacterium Shigella dysenteriae (in collaboration with Saul Tzipori, Tufts Cummings School of Veterinary Medicine).

In addition to proteome profiling, the PFGRC Proteomics Group is developing high throughput platforms for in vitro and in vivo protein expression and purification utilizing the Gateway® Destination Vector System.  Proteins expressed and purified in this manner will be targeted for specific applications utilizing protein microarrays.
