Voltage and current clamp recordings of Cor.4U® human iPS cell-derived cardiomyocytes using Sophion’s QPatch


Sophion application report


Daniel Sauter



  • High fidelity voltage and current clamp recordings of Cor.4U in physiological solution
  • Demonstration of the presence of INa, ICa as well as IKr
  • The use of fluoride in the internal solution resulted in lower
    ICa and shortened action potential durations
  • Paced and spontaneous action potentials
  • Pharmacological agents show expected effects on action
    potentials in Cor.4U
