Mass spectrometry is a core enabling technology for proteomics with proteins identified by molecular weight, mass maps and sequencing within the confines of a mass spectrometer. We have found conditions under which it is possible to preserve and detect protein complexes by matrix-assisted laser desorption ionization (MALDI) mass spectrometry that has promising implications for the high-throughput screening of protein-protein interactions. Technologies pioneered by the applicant will be advanced to achieve the high-throughput analysis of antibody complexes with native gel recovered protein antigens across emerging strains of the influenza virus by means of miniature protein chips.Read moreRead less

This will be the first and only multi-user facility of its type in Sydney. It will provide through its synthetic node at NSW and Macquarie Universities and biological screening node at University of Sydney an essential resource that will enable modern combinatorial techniques to be applied to chemical and drug-lead development studies in the region.Read moreRead less
Characterising post-translational modifications in bacterial proteins. This project represents the first global attempt to characterize post-translational modifications in bacterial proteins using the tools of proteomics. Modifications to proteins are key elements in altering their function. In bacteria, modifications are important in cell-cell adhesion, signalling and triggering of the immune response. Characterisation of modified proteins and their sites of modification represents an opportuni ....Characterising post-translational modifications in bacterial proteins. This project represents the first global attempt to characterize post-translational modifications in bacterial proteins using the tools of proteomics. Modifications to proteins are key elements in altering their function. In bacteria, modifications are important in cell-cell adhesion, signalling and triggering of the immune response. Characterisation of modified proteins and their sites of modification represents an opportunity to understand how bacterial cell populations communicate in the environment, as well as aid in understanding pathogenesis in medical, veterinary and food-borne pathogens. Therefore, improved vaccine targets and therapeutics, as well as method-based products, may be generated by this project.Read moreRead less

Summary
NMR cryosystem for structural and functional biology. State-of-the-art hardware is requested for the 600-MHz NMR spectrometers situated at University of Sydney and UNSW. A cryosystem installed at USyd. will provide a massive boost in productivity and will allow projects previously inaccessible due to excessive turn-around times, or sensitivity or solubility problems to become tractable. This system will provide new opportunities to researchers from USyd., UNSW and ANU, but will restrict the ver ....NMR cryosystem for structural and functional biology.

This system will provide new opportunities to researchers from USyd., UNSW and ANU, but will restrict the versatility of the USyd. instrument. The installation of a TBI probe at UNSW will counter this, and provide a REAL network of NMR instruments across NSW and the ACT.Read moreRead less

The Application of Chemical Force Microscopy for Monitoring DNA Hybridization: A New Sensing Concept Capable of Detecting Single Molecules. This proposal outlines a method of monitoring DNA sequences with such high sensitivity that a single molecule may be detected. Such sensitivity is achieved using an atomic force microscope (AFM) to measure surface forces. Modifying an AFM tip with a single strand of DNA allows the complementary strand (the target) to be recognized via hybridization to form ....The Application of Chemical Force Microscopy for Monitoring DNA Hybridization: A New Sensing Concept Capable of Detecting Single Molecules. This proposal outlines a method of monitoring DNA sequences with such high sensitivity that a single molecule may be detected. Such sensitivity is achieved using an atomic force microscope (AFM) to measure surface forces. Modifying an AFM tip with a single strand of DNA allows the complementary strand (the target) to be recognized via hybridization to form the double helix. The occurrence of hybridization is determined by differences in surface force measurements compared with when only the single strand of DNA is present. In this way DNA samples can be analyzed without amplification; a major advance for DNA diagnostics.Read moreRead less
Nucleotides for bioelectronics. Bioelectronics is a key component of nanobiotechnology, a new field that merges the science of biological molecules (DNA, proteins etc.) with electronics and semiconductor physics. We have recently introduced redox-labelled nucleotides that enable the production of electrochemically-active DNA and RNA for genetic, forensic and nanotechnology applications. This project further develops redox nucleotides for use in electronic devices.
