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.
Software
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.
Statement about the DataControl 96 Package
Hans-Peter Scholz - Statement about the Analysis Software of the CardioExcyte 96 "DataControl 96"
“DataControl 96 allows us to analyze large amounts of data and represents a huge step towards standardized experiment analysis. All the well's individual raw data, analysis results, concentration response curves and also the fits averaged per compound are displayed on a single screen, which means that all relevant information is right at the place where we want to see it. Analysis templates can be used to re-do the same analysis procedures on a different compound, but same target, thus reducing the effort for data handling to just a couple of mouse clicks. Powerful averaging with standard deviation display and referencing methods allow for great quality control. Furthermore, multiple export options are available to allow a seamless integration in databases.”

Testimonials & Case Studies
Prof. Bjorn C. Knollmann - Statement about the CardioExcyte 96
“We are happy to have acquired the CardioExcyte 96 from Nanion and look forward to publishing the first of many papers. We looked at several different devices on the market but were impressed by the resolution and ease-of-use of the CardioExcyte 96 and Nanion’s enthusiasm and friendly customer support. I was particularly intrigued by the pacing feature, the single electrode design giving better signal to noise ratio, the dual EFP + impedance capability, and the environmental chamber so that you can run everything on the benchtop. The new optical pacing feature added in 2017 has further expanded the utility of the instrument for drug testing and disease modeling: For the first time, rate-dependent changes of cardiac electrophysiology and contractility can be easily quantified.”
Prof. Bjorn C. Knollmann, Director of the Center for Arrhythmia Research and Therapeutics of Vanderbilt University School of Medicine:
Marc Rogers - Statement about the Patchliner and CardioExcyte 96
"It has been an absolute pleasure and privilege to work with Niels and the Nanion team over the past decade. I firmly believe that our two small, but independently minded ion channel focused companies, share a similar business ethos and a clear focus on delivering cost-effective solutions to our customers. In our extensive use of the Patchliner platform since 2007, my teams have benefited from the dedication of Nanion’s service engineers, application scientists, and bespoke data acquisition routines, whilst Nanion have benefited from seeing their products applied and adapted to real-world drug discovery projects and assays."
"This fruitful working relationship has now been extended to our use of the CardioExcyte96 phenotypic assay platform, which we utilise to develop and validate human iPSC cardiomyocyte cell lines and assays to meet the post-hERG, predictive cardiac safety testing needs of the drug discovery industry”."

Dr. Ralf Kettenhofen - Statement about the CardioExcyte 96
"CardioExcyte 96 is an easy-to-use system, providing impedance-based and MEA-like cardiac safety data from a diversity of stem cell-derived cardiomyocytes, and constitutes an excellent complement to automated patch clamp-based safety screening. Concentration- and time-dependence of a compound’s potential cardiotoxicity can efficiently be obtained where the alteration of beating patterns can give a hint as to which cardiac ion channel(s) is affected, after which detailed electrophysiology investigations can be undertaken. Cardiac network responses offer a comprehensive view of a compound’s safety profile, without having to use in-vivo methods, which saves time, costs and suffering. Further on, the powerful software, used for recordings and analysis, employs comprehensive beat investigation algorithms, displaying detailed beating kinetics in real-time. Data handling and export is straightforward, easy to grasp and yet very, very powerful."

Cardiomyocytes - Time-dependent effect of Pentamidine on Cor.4U cardiomyocytes
CardioExcyte data and applications:
Cells were kindly provided by Axiogenesis.
Time-dependent effect of Pentamidine on Cor.4U cardiomyocytes. Pentamidine clinically causes acquired long QT syndrome, which is associated with prolonged QT intervals, tachycardias, and sudden cardiac arrest. Pentamidine delays terminal repolarization in human heart by acutely blocking cardiac inward rectifier currents. At the same time, it reduces surface expression of the cardiac potassium channel IKr/human ether à-go-go-related gene (hERG).
Insets: EFP raw traces and online analysis value FPDc in the presence of Pentamidine (10 µM) at different timepoints.
Cardiomyocytes - Tetracaine dose response curves as recorded with Cor.4U cells
CardioExcyte 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.
Cardiomyocytes - Nifedipine and its concentration dependent effect on Cor.4U cells
CardioExcyte data and applications:
Cells were kindly provided by Axiogenesis.
Nifedpinie is a dihydropyridine calcium channel blocker that primarily blocks L-type calcium channels. Impedance and EFP recordings on Cor.4U cells reveal a concentration dependent effect on impedance amplitude, beat rate and also a shortening of the FPD as expected.

Murine Mammary Carcinoma Cells - Effect of CAF (cyclophosphamide, adriamycin (doxorubicin) and 5-fluouracil)
CardioExcyte data and applications:
Data kindly provided by Oliver Reinhardt, MPI Experimentelle Medizin, Göttingen
Murine mammary carcinoma cells (H8N8 and H8N8 T3.2) were monitored over a time period of 500 h. Changes in impedance, and therefore confluency, were used as a measure of toxicity.
H8N8 cells have been developed as a tool to investigate tumor cell recurrence, chemoresistance and epithelial-to-mesenchymal transition (EMT). Cells were treated with increasing concentrations of CAF (cyclophosphamide, adriamycin (doxorubicin) and 5-fluouracil) on the CardioExcyte 96 during impedance measurements. Therefore, the CardioExcyte 96 in combination with murine mammary carcinoma cells provides a novel tool for investigating therapy resistance of cancer cells in vitro.

Hepatocytes - Paracetamol toxicity on hepatocyte-like MetaHeps cells
CardioExcyte data and applications:
Cells were kindly provided by MetaHeps.
The impedance signal recorded on the CardioExcyte 96 changes as a result of alterations in confluency, cell contact (morphological shape) and conductivity of adherent cells and thereby provides a measure of toxicity. MH cells from MetaHeps® were grown on NSP-96 plates and base impedance was monitored over time. Increasing concentrations of paracetamol induce a decrease in base impedance of MH cells which can be monitored continuously. Tween (2%) induced 100% cell death and was used as a positive control.
