Cysteine proteinase RgpB and carboxypeptidase CPG70 as candidate antigens for Porphyromonas gingivalis vaccine. (multiple projects)*

Cysteine proteinase RgpB and carboxypeptidase CPG70 purified from P. gingivalis have been shown to protect animals from live P. gingivalis challenge in a murine lesion model (unpublished data). We are currently characterizing the resulting protective antisera using various approaches. The resulting antisera could also be used for further characterization of the two enzymes, including their possible interactions with host extracellular matrix proteins. Multiple projects are available and the techniques involved will depend on the project undertaken. The techniques could involve protein purification, enzyme activity assays, gel electrophoresis, ELISA, Western blots, mass spectrometry (MALDI-TOF-TOF and nanoLC-Ion Trap) and BIACORE 3000.

Proteomics of P. gingivalis*

We have one of the most advanced proteomics labs in Australia, housing the first Australian MALDI TOF/TOF mass spectrometer as well as two LC-MS systems, a standard MALDI TOF and robotics for sample preparation. The honours student who takes on this project will receive in-depth training in proteomics while making an important contribution to our studies. A variety of specific projects could be tailored to suit your interests.
