This proposal aims to exploit a novel platform for parallel on-chip electrophysiology, developed at the University of Southampton, for the functional characterization of a family of voltage-gated sodium channels, including human/bacterial chimeras, for which the expression, purification and reconstitution into liposomes is being developed at Birkbeck College. Specifically, the project will use this high-throughput platform to identify novel ligands/drugs that modulate the conductance properties of the sodium channels.
