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.
Recordings using voltage-sensitive dye (VSD) with quality equivalent to patch-clamp are crucial for assessing cardiovascular risk in drug discovery. They provide a high-fidelity, high-throughput alternative to traditional electrophysiology techniques.
VSD-based recordings offer non-invasive, high-resolution measurements of membrane potential changes across a large number of cells or wells simultaneously, enabling faster and more efficient cardiac safety screening. This approach ensures precise detection of drug-induced effects on cardiac ion channels, such as hERG (IKr), Nav1.5, and Cav1.2, which are critical for evaluating proarrhythmic risk.
The ability to achieve patch-clamp-equivalent data quality using VSD enhances predictive accuracy, reducing false negatives and late-stage failures, and supports safer drug development with improved preclinical-to-clinical translation.

Metrion and Sophion collaborated to determine whether other insoluble salts can act as seal enhancers, or whether this property is unique to CaF2.
