The HESI Cardiac Safety Committee present results from an international ion channel research study that assessed the variability of hERG data generated using automated patch clamp platforms (QPatch 48, Qube 384 and the SyncroPatch 384i) across four different labs.
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).
Highly specialised and tailored neuronal assays for pharmacological screening.
Reliably evaluate the proarrhythmic and cardiotoxic liabilities of your compounds.
Specialist ion channel screening to accelerate early-stage screening and lead optimisation.
We report the development and optimisation of a TREK-1 functional assay using the Qube 384, an automated patch clamp platform capable of supporting high-throughput screening. The assay was optimized to identify both activators and inhibitors on the same plate, providing key mechanistic data for high value, limited supply screening libraries such as venom fractions used in this study (Targeted Venom Discovery Array, TVDA, 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.
KV3.1 is a voltage-gated potassium channel encoded by the KCNC1 gene. Mutations in the KV3.1 protein can manifest as a variety of neurological disorders including myoclonic epilepsy and ataxia due to K+ channel mutation (MEAK), developmental epileptic encephalopathy (DEE), or hypotonia.
