Improve efficiency, reduce late-stage failures, and align with regulatory standards by assessing the proarrhythmic liability of your compounds early. The potency data derived from high-fidelity platforms such as automated patch-clamp and the gold standard manual patch-clamp technique, is suitable for use in in silico action potential models. Our full cardiac ion channel panel includes: hERG (including a robust, dynamic hERG assay), KVLQT1/mink, hKV4.3/KChIP, hCaV1.2, hNaV1.5 (peak and late), hKIR2.1. Screening services against hHCN4 and hKV1.5, which play important roles in controlling human heart rate and atrial repolarisation, respectively, are also provided.

Optical voltage imaging of human iPSC-derived cardiomyocytes was used to assess electrophysiological effects of compounds beyond hERG inhibition. Action potential waveform analysis revealed compound-specific and concentration-dependent changes, enabling mechanistic differentiation of multichannel activity and demonstrating a human-relevant approach for translational cardiac safety assessment.
