CardioExcyte 96 – Combined contractility, electrophysiology and cell viability
The CardioExcyte 96 is a hybrid system recording both contractility and electrophysiology of intact cardiomyocyte networks. In addition, the base impedance is continuously and automatically monitored as a measure of acute and chronic cell activity. No subtleties of cytotoxic responses are missed, this includes non-contractile cell types such as hepatocyte-like cells or cancer cells as well as contractile cardiac cells. Impedance and extracellular field potential measurements are performed at high resolution, are non-invasive and label-free. The CardioExcyte 96 is a fully automated device, recording from 96 wells at a time. The benefits the CardioExcyte 96 offers include:
- NEW Add-On! FLEXcyte 96 for Contractility under physiological conditions!
- Impedance & extracellular field potentials from the same well
- 96 recording wells in parallel
- Non-invasive & label-free measurements
- High resolution
- Electrical and optical pacing options
- Acute and chronic assessment of cell activity and toxicity
- Part of the CiPA validation study
With embedded electronics and a sophisticated sensor technology integrated in the well-plate based consumables, the CardioExcyte 96 is a turn-key system for efficient impedance and extracellular field potential measurements. The CardioExcyte 96 package includes an Incubation System which makes the system independent of an incubator. The system is placed on the bench top with maintained control over temperature, gas mix and humidity.
Efficiency and ease-of-use are facilitated by an outstanding software package for data handling and export - an essential part of the CardioExcyte 96 system. The system has been validated with stem cell-derived cardiomyocytes from all major stem cell providers, as monolayers or beating 3D-clusters, as well as with cell lines (hepatocyte-like cells, cancer cells etc.) for cytotoxicity studies.

Add-Ons and Features
CardioExcyte 96 Platform
The CardioExcyte 96 package contains an Integra Viaflo Assist that provides automated multichannel pipetting for reproducible 96 well plate handling of cells and compounds.
CardioExcyte 96 Incubation System
The CardioExcyte 96 package includes an Incubation System. This means that the measurements are performed outside the cell culture incubator and the complete setup fits on a lab benchtop. The CardioExcyte 96 Incubation System controls temperature, gas mix and humidity.
CardioExcyte 96 SOL (Add-On)
Optical stimulation and investigation of impedance and extracellular field potentials in parallel:
The stimulating optical lid, CardioExcyte 96 SOL, uses LEDs for spatially uniform stimulation of cells transfected with light-gated ion channels such as Channelrhodopsin2 (ChR2). After transfection of iPS cardiomyocytes with ChR2 the cells can be stimulated by blue light. Each light impulse induces a depolarization of the cells and thus an action potential is triggered. The advantages of optical stimulation over electrical stimulation include the highly precise timing, all cells of the beating network are stimulated exactly at the time of the light stimulus. In contrast, electrical stimulation propagates from the electrode across the well and thus cells are stimulated progressively. A mean beat calculation of precisely timed beats enables in-depth compound analysis and concentration response dependencies to be obtained. This is one of the key software capabilities of the CardioExcyte Control/ DataControl software package that is provided with each CardioExcyte 96 system.
CardioExcyte 96 Software package
The CardioExcyte Control software supports online analysis of beating parameters. The unique Mean Beat Function automatically visualizes the average of beat traces from one well, enveloped by the standard deviation, indicating the consistency of the beat pattern within the recording well, i.e. if the cellular network is synchronously beating or not. The control software is intuitive and easy-to-use, at the same time very powerful in terms of experimental setup and online visualization of the recorded data.
The DataControl 96 software package is an independent software package to load and analyze data recorded on the CardioExcyte 96.The analysis template can be saved and reloaded. Customized export formats of analysis results are integrated.
The Online Analysis Post Processor (OAPP) is a software tool enabling quick visualization of well-to-well statistics and concentration dependent effects. Parameters and traces can be normalized to control values or time points. Export of graphics is straightforward making OAPP a highly versatile tool for the analysis routine.
