The BDI's Biorecognition research focuses on the production of diverse antibody libraries against clinically relevant biomarkers of disease (e.g. cardiac disease; inflammation; prostate, colon and pancreatic cancer), food and environmental toxins, pathogens (e.g. listeria), and drugs. The programme involves the development and optimisation of a fully automated protocol for antibody screening and selection including the full characterisation and immunoassay performance of selected antibodies. In addition, genetic engineering techniques are utilised to further enhance the specificity and sensitivity of the antibodies and fragments. These optimised antibodies are integrated with developments from other BDI programmes to yield the extremely high levels of performance required for Point of Care (POC) devices. Antibodies generated have been successfully integrated into clinically validated platforms that are now commercially available.
In addition, significant research has focused on the use and characterization of avian-derived antibodies due to their enhanced stability, ease of manipulation and large-scale production. There is also a focus on developing bispecific antibodies with potential clinical applications in cancer therapy.
Key programme elements:
These programme elements include the provision of large panels of fully engineered and characterised antibody fragments to multiple biomarkers. Molecular engineering techniques are being utilised to enhance and continually evolve selected antibody characteristics for immunoassay applications including the fundamental elements that contribute to the efficiency of ligand generation, stability and post-immobilisation activity.
