Diagnostics - Mologic and Affimers20 Feb 2022 05:14
This project will be delivered in partnership with Mologic and Tomlinson lab. With mologic now acquired by Gates I'd say its far from over for the Dx division.
Affimers are renewable, recombinant, molecular recognition reagents with diverse applications within molecular and cellular biology, including the study of protein localization, protein function and protein-protein interactions.
Affimer production is highly scalable and reproducible, and combined with their high stability and target specificity, they represent excellent alternative non-antibody tools for the development of molecular detection assays, such as point-of-care LFDs.
Objective
Focusing on selected viruses listed on the World Health Organization (WHO) R&D blueprint (Lassa, Ebola, Rift Valley fever and Crimean-Congo hemorrhagic fever viruses) we will isolate Affimers that bind their respective spike proteins and other relevant proteins such as nucleoproteins, with the aim of developing a multiplexed pathogen detection platform for the diagnosis and differentiation of the corresponding diseases. Development of an Affimer- based diagnostic platform would meet the challenge of the WHO R&D blueprint, and also break the reliance on animal-based antibody production, which is a goal of the BBSRC transformative technologies priority.
The spike-specific Affimers we generate will be also assessed for their ability to neutralize virus infectivity. Structural and functional studies of the spike- Affimer complex will be performed to dissect the molecular basis for neutralization, with the potential to identify sites critical for spike function.
