Easy-to-use software enabling robust and high-throughput cardiotoxicity screening using the FLIPR Penta system


Bring simplicity to your multi-user environment with unique protocols utilizing ScreenWorks® Software on the FLIPR® Penta High-Throughput Cellular Screening System. The software controls equipment intelligence and instrument motion as well as capturing data for analysis and export during highly kinetic assays. It records the signal from both standard GPCR assays in fluorescent or luminescent format and up to 100 fluorescent images per second during an iPSC cardiomyocyte fast calcium oscillation assay. The optional add-on, Peak Pro 2 software module, enables you to perform advanced peak analysis. It is especially helpful for analysis of iPSC derived cardiomyocyte and neuron calcium oscillation assays.

High-throughput early toxicity screening with optional Peak Pro 2 software module


Advanced peak detection and event characterization measurements and analysis functionality are available with the optional Peak Pro 2 software module. This data analysis capability is especially useful with cardiomyocyte and neuronal protocols. The Peak Pro 2 analysis algorithm reduces false detections without the need to condition the raw data using search vectors.

The FLIPR Penta system with high-speed camera (HS EMCCD) option, for monitoring calcium oscillation in response to GPCR and ion channel modulator with Peak Pro 2 software module, allows you to measure and analyze patterns of calcium oscillations before and after treatment of human iPSC-derived cardiomyocytes and neurons. Images can be taken up to 100 times per second. You can analyze patterns using more than 30 parameters.

New safety measures in the drug discovery world, such as the NIH CiPA initiative, have placed added emphasis on early assessment of clinical safety and potential. The instrument hardware flexibility and easy-to-use Peak Pro 2 software module can help you assess and quantitate oscillation patterns consistent with potential cardiotoxicity earlier in the drug discovery process. It is also possible to characterize Ca2+ oscillation patterns in neuronal cells and spheroids. Panel A shows some of the parameters that you can measure. Panel B shows control and two examples of oscillation patterns.

Applications of ScreenWorks Software

  • Calcium Flux

    Calcium Flux

    The evaluation of calcium flux is a long accepted, tried and true measure of cellular activity. Calcium flux can be used as a measurement for a host of cellular processes including neurotransmitter release, GPCR activity, voltage or ligand gated ion channels, and cardiomyocyte beat patterns, among many others. The FLIPR Penta System is the drug discovery tool for evaluation of calcium flux in high and ultra-high throughput due to its ease of use, sensitivity and user configurability.

    Cardiomyocyte screening

    Cardiomyocyte Screening

    Early prediction of drug-induced functional cardiotoxicity requires robust in vitro systems suitable for high-throughput screening. Readily-available iPSC-derived human cardiomyocytes may be used in conjunction with calcium-sensitive dyes, and beat rates are monitored as changes in intracellular calcium. These calcium peaks can be analyzed with our ScreenWorks PeakPro software which provides the investigator a suite of powerful tools for quantification of cardiomyocyte activity.

  • Cardiotoxicity

    Cardiotoxicity or Cardiac Toxicity

    Cardiotoxicity or cardiac toxicity is a term used to define chemicals that are toxic to the heart, causing muscle damage or heart electrophysiology dysfunction.

    The assessment of cardiotoxicity is important in the early stages of drug discovery to eliminate potentially toxic compounds from further development.

    GPCRs (G protein-coupled receptors)

    GPCRs (G protein-coupled receptors)

    GPCRs or G protein-coupled receptors are proteins located on the cell surface that recognize extracellular substances and transmit signals across the cell membrane. GPCRs do this by activating guanine nucleotide-binding proteins (G protein) that are responsible for signal transduction inside the cell.

  • Ion Channel

    what are Ion Channel

    Ion channels are pores in the cellular membrane that allow the passage of ions across the impermeant lipid cell membrane. The flow of calcium, potassium, and sodium is very important in many cellular processes such as muscle contraction in the heart, pancreatic insulin release, the transmission of impulses in the nervous system such as pain, and T cell activation.

    Membrane Potential

    Membrane Potential

    There are dozens of identified disorders caused by impaired ion channel function. Ion channels are important drug discovery targets because they are highly druggable and specific. The FLIPR® Membrane Potential Assay Kits provide a fast, simple and reliable fluorescence-based assay for detecting changes in voltage across the cell membrane mediated by ion channel to evaluate target or off-target effects based on the application.

  • Neuronal assays

    Neuronal Assays

    The FLIPR Penta System is an excellent tool for monitoring calcium flux related to neuronal activity. Newly developed commercially available iPSC neurons have made high-throughput neuronal screening a reality. These cells and assays are essential for monitoring a variety of factors including neural cell culture conditions, drug compound effects, and the effect of environmental neurotoxins. Neuronal activity and neurotransmitter release can be evaluated with fluorescence-based calcium indicator dyes combining fast, simple, and powerful assays with scalable throughput.

    Potassium Assays

    Potassium assays

    The majority of ion channel drug discovery solutions focus on potassium channels since they are the most prevalent type of ion channel, functioning in cardiac muscle action and hormone release. Potassium assay kits can be used to measure the effect of drug molecules on thallium transport through the potassium channel as a surrogate for potassium channel activity.
