Characterization of Ion Channels in Stem Cell-derived Cardiomyocytes on An Automated Parallel Patch Clamp System 22 Jun 2010: In this application note Molecular Devices use the PatchXpress 7000A automated parallel patch clamp system is used to record Na, K and Ca currents from stem cell-derived mouse cardiomyocytes. The collaborative effort demonstrates that the combination of “ready-to-use” cardiomyocytes with an automated patch clamp system offers a powerful assay platform for fast assessment of compound efficacy and for safety profiling of lead compounds in a biologically relevant system.
