Cardiomyocytes - Tetracaine dose response curves as recorded with Cor.4U cells

Icon CE   Tetracaine Cor4UCardioExcyte data and applications:
Cells were kindly provided by Axiogenesis.

Impedance amplitude is not changed by addition of increasing concentrations of Tetracaine (left panel), while beat rate of Cor.4U® cells is decreasing. For example, 29.6µM of Tetracaine decreased the beat rate by ~60% when compared to pre-addition values. Cumulative dose-response relationships indicate Tetracaine potency for same-well additions. Representative raw traces for impedance signals (middle panel) clearly indicate a decrease in cell monolayer beat rate with increasing concentrations of Tetracaine.
Extracellular Field Potential (EFP) spike amplitude is decreased by cumulative Tetracaine dose applications to the same monolayer of Cor.4U® cardiomyocytes (top right), in agreement with compound mechanism of action. Representative raw traces for EFP signals (bottom graph) clearly indicate a decrease in spike amplitude.
