WebThe Maestro reliably detected field potential duration (FPD) prolongation for hERG K+ blockers, FPD reduction for Ca2+ blockers, and spike amplitude reduction for Na+ blockers across sites and cell types. In the multi-site, blinded CiPA Pilot Study, the CiPA team demonstrated the utility of hiPSC-cardiomyocytes to detect cardioactive compounds. WebThe time from the depolarization to repolarization is termed the field potential duration (FPD) and is a key metric in predictive cardiotoxicity screening assays. While most record the cardiac field potential, the Maestro Pro and Edge MEA systems can also measure local extracellular action potentials, or LEAP. prenninger thomas https://organiclandglobal.com
