The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

A New Scrambled Antigen Vaccine (SAVINE) Approach: Proof-of-concept In Non-human Primates For HIV-1
Funder

Funding Amount
$120,700.00
Summary
The specific aim of this proposal is to demonstrate, in non-human primates, proof–of-concept of a patented new platform vaccine technology (scrambled antigen vaccine or SAVINE) designed to encode all the protein sequences of an infectious agent, in this case HIV-1. These are arranged as equal-sized, overlapping fragments such that all potential T cell epitopes that are needed to induce broad T-cell-mediated immunity are maintained. The synthetically designed vaccine uses consensus sequences of H ....The specific aim of this proposal is to demonstrate, in non-human primates, proof–of-concept of a patented new platform vaccine technology (scrambled antigen vaccine or SAVINE) designed to encode all the protein sequences of an infectious agent, in this case HIV-1. These are arranged as equal-sized, overlapping fragments such that all potential T cell epitopes that are needed to induce broad T-cell-mediated immunity are maintained. The synthetically designed vaccine uses consensus sequences of HIV-1 to provide universal coverage of the major HIV-1 strains for a global population. The synthetic systematically designed HIV-1 vaccine will be delivered using our newly developed prime-boost immunisation regime that induces particularly high levels of cell-mediated immunity.Read moreRead less
Characterisation Of A Novel Direct Electrochemical Chip As A Biosensor And Tool For Studying Redox-sensitive Proteins

Summary
Biosensors use biomolecules to detect a chemical event. They are becoming important for the rapid and reliable measurement of the concentrations of molecules in fluids. In human medicine they will be of great use to general practitioners and patients for instantaneous read outs of concentrations of many different biological molecules. How well a biosensor responds depends on the method in which the biomolecule is immobilised to a surface and the signal detected. We have made a significant advanc ....Biosensors use biomolecules to detect a chemical event. They are becoming important for the rapid and reliable measurement of the concentrations of molecules in fluids. In human medicine they will be of great use to general practitioners and patients for instantaneous read outs of concentrations of many different biological molecules. How well a biosensor responds depends on the method in which the biomolecule is immobilised to a surface and the signal detected. We have made a significant advance in biosensing capabilities using a recombinant protein (thioredoxin) and demonstrated the improvement that is possible by (i) immobilising the protein in a highly oriented way and (ii) using a sensitive electrical signal to monitor the response. Here we will undertake more comprehensive testing by extending the number of proteins to include the 4 major classes of redox-sensitive biomolecules (proteins) in the body. This will enable us to establish the broad application of our methods and substantially improve our ability to commercialize our discoveries.Read moreRead less
A Novel Vaccine Platform For Trimeric Envelope Proteins: HIV-1 Envelope
Funder
National Health and Medical Research Council
Funding Amount
$139,250.00
Summary
Vaccines are urgently needed for the prevention of HIV/AIDS. The design of this vaccine candidate is based on the display of HIV-1 envelope spikes using a related primate retrovirus envelope with a more stable assembly to anchor the the spikes in a particle.
