Ion channels represent 15 – 20% of historic drug approvals and recent drug discovery projects. Many ion channel families (Nav, Cav, TRPx and GABA) are validated as therapeutic targets based on human genetics, animal models and selective pharmacology. However, ion channels are challenging targets requiring expert target class knowledge and specialised screening technology such as automated patch-clamp (APC) electrophysiology.
We developed a high-throughput, electrophysiological assay of TREK-1 function to identify novel modulators. The assay was optimized to identify both activators and inhibitors, providing comprehensive mechanistic data for high value, limited supply screening libraries, such as the venom fraction library used in this study (Targeted Venom Discovery Array, T-VDA, Venomtech, UK).
Scientifica’s PatchScope Pro is an integrated electrophysiology rig incorporating an inverted phase-contrast fluorescence microscope, motorised XY stage and PatchStar micromanipulators, suitable for patch-clamp recording.
