This project aims to address the challenge of in-situ quantification of membrane proteins through the emerging field of antibody-imaging mass spectrometry. The project will develop new protocols for quantitative three-dimensional imaging that aim to negate histological artifacts created by freeze-thaw and cryo-sectioning. Membrane proteins are involved in numerous cellular functions and this project expects to increase our knowledge of these fundamental biological processes by providing new insights into the study of these essential biomolecules. Tracking protein heterogeneity in three-dimensions will provide significant benefits to our understanding of systems biology and will benefit numerous area, including the pharmaceutical industry.Read moreRead less
Developing next-generation mass spectrometry imaging with isomer resolution. Mass spectrometry imaging (MSI) is a rapidly emerging technology for mapping molecular distributions within biological samples. This project will bring together market-leading MSI instrumentation from the industry partner Waters Corporation with unique technologies developed at QUT and UOW to develop an integrated MSI-platform capable of achieving high mass- and spatial-resolution, as well as discrimination of lipid iso ....Developing next-generation mass spectrometry imaging with isomer resolution. Mass spectrometry imaging (MSI) is a rapidly emerging technology for mapping molecular distributions within biological samples. This project will bring together market-leading MSI instrumentation from the industry partner Waters Corporation with unique technologies developed at QUT and UOW to develop an integrated MSI-platform capable of achieving high mass- and spatial-resolution, as well as discrimination of lipid isomers. Resolution of lipid isomers using this instrumentation will afford researchers a first glimpse of isomer-resolved images that will be used to visualise tissue-specific changes resulting from underlying chemical, physical or metabolic processes; changes that are currently invisible to contemporary imaging technologies.Read moreRead less
Pluses and minuses of lipid mass spectrometry. This project aims to investigate the structural diversity of lipids. Lipids are among the most structurally diverse of all the biomolecules and thus deciphering their many functions requires bio-analytical technologies capable of uniquely identifying and quantifying individual molecules in a milieu of many thousands of analogues. Mass spectrometry is the pre-eminent technique for contemporary lipid analysis but is challenged by the preference of cer ....Pluses and minuses of lipid mass spectrometry. This project aims to investigate the structural diversity of lipids. Lipids are among the most structurally diverse of all the biomolecules and thus deciphering their many functions requires bio-analytical technologies capable of uniquely identifying and quantifying individual molecules in a milieu of many thousands of analogues. Mass spectrometry is the pre-eminent technique for contemporary lipid analysis but is challenged by the preference of certain lipids to ionise with a polarity that affords sensitive detection but does not permit detailed structure elucidation. This project will develop advanced instrumentation capable of on-demand polarity switching of ionised lipids such that the detection and interrogation of molecular structure can take place in the optimal charge state.Read moreRead less
Developing next generation technologies for unmasking the lipidome. Recent discoveries suggest that the number and structural variety of lipids in nature may be far greater than previously imagined. This complexity arises from the presence of structurally similar, but functionally distinct, lipid isomers that are not readily distinguished using current lipidomics technologies. This project aims to develop unique instrumentation that combines ion mobility and mass spectrometry to enable the rapid ....Developing next generation technologies for unmasking the lipidome. Recent discoveries suggest that the number and structural variety of lipids in nature may be far greater than previously imagined. This complexity arises from the presence of structurally similar, but functionally distinct, lipid isomers that are not readily distinguished using current lipidomics technologies. This project aims to develop unique instrumentation that combines ion mobility and mass spectrometry to enable the rapid separation, identification and quantification of isomeric lipids. These next generation technologies will be deployed in the hope of unmasking the molecular diversity within the lipidomes of two important mammalian cell types, thus providing fundamental new insights into the structure and function of lipids within living systems.Read moreRead less
Development of ozone-induced dissociation for lipidomics workflows. An Australian invention (ozone induced dissociation) will be developed in collaboration with a major instrument manufacturer. This project will provide Australian researchers with unique capabilities to investigate the role of lipids (fats) in human disease and will place them at the forefront of lipid research internationally.
Development of an ultrasensitive assay for human prion proteins. The aim of this work is to enable the detection of prion proteins in human blood and other tissues. The assay system to be developed will detect much lower levels of these disease-causing proteins than is possible at present; it will be more rapid and will measure prion protein levels more accurately than existing assays. The outcome of the work is expected to facilitate the production and certification of prion-free blood and bl ....Development of an ultrasensitive assay for human prion proteins.

The assay system to be developed will detect much lower levels of these disease-causing proteins than is possible at present; it will be more rapid and will measure prion protein levels more accurately than existing assays. The outcome of the work is expected to facilitate the production and certification of prion-free blood and blood products. Prions cause Bovine Spongiform Encaphalopathy and Creutzfeld Jacob Disease and attempts to control of these diseases would be greatly abetted by an optimal test for the disease-causing agent.Read moreRead less
