Figure 1: Measurement of Action Potentials of 2D Cardiomyocyte Cultures with an LVF Monochromator or Optical Filters. A) Action potentials from 2D monolayer cardiomyocyte culture using the CLARIOstar® with LVF Monochromator without filters. Average trace on the right with error bars (SEM). B) Action potentials measured from 2D monolayer cardiomyocyte culture using the CLARIOstar® with an excitation filter at 482-16 nm and emission filter at 530-40 nm with a long-pass dichroic filter at 504 nm. Average trace on the right with error bars (SEM).
