We demonstrate the generation and validation of a stable CHO-hHCN2 cell line used as a cellular tool in the successful development of hHCN2 automated electrophysiology screening assays.
Ion channels play a key role in regulating resting membrane potential and cell excitability and are attractive targets for therapeutic intervention.
Thallium (Tl+) flux assays, which measure the flow of Tl+ through potassium channels, offer a high throughput method for the identification of potassium channel activators. However, these assays are a surrogate for channel function and it is important to have an appropriate panel of orthogonal and translational electrophysiology assays in place to confirm activity at the channel of interest.
We demonstrate the generation and validation of a stable CHO-hHCN2 cell line used as a cellular tool in the successful development of hHCN2 automated electrophysiology screening assays.
We have developed a robust high-throughput automated electrophysiology assay using a monoclonal CHO-hNav1.9 cellular reagent suitable for fully supporting a Nav1.9 discovery program.
