In this video, spontaneously beating human stem cell-derived cardiomyocytes stained with ElectroFluor630TM allows ratiometric optical action potential recordings. The ratio of two excitation wavelengths boosts signals and removes artifacts due to non-uniform staining, bleaching, and the motion of these beating (contracting) human heart cells in a dish.
