Maestro TrayZ

Axion BioSystems Maestro TrayZ

Maestro TrayZ

The Maestro TrayZ™ is a sensitive, live-cell impedance platform for real-time measurement of cell health and function. Continuously monitor up to four 96-well plates simultaneously and generate accurate, reproducible kinetic data using cellular impedance. It features a slim, multiplate tray designed to easily fit in an incubator without requiring the whole incubator.

With easy-to-run assays and clear results, the Maestro TrayZ platform is ideal for cytotoxicity, cell growth, adhesion, immune cell-mediated killing, TEER/barrier function, wound healing, GPCR signaling, viral cytopathic effects, and more. Save time, cut costs, and simplify your workflow with Maestro TrayZ.

For Research Use Only. Not for use in diagnostic procedures.

Key Features


  • >> Continuous live-cell monitoring - The Maestro TrayZ platform performs noninvasive, label-free electrical measurements from the cultured cell population, circumventing the use of dyes/reporters that can perturb your cell model and confound results. Track activity in real time over hours, days, and weeks.
  • >> Expand to meet your needs - With one tray, measure up to four plates at once, or link multiple trays together to increase your throughput to meet your needs.
  • >> Manage multiple experiments at the device  - Barcode tracking ensures there are no mix-ups. As soon as a plate is docked, recording begins without having to run back and forth to a computer.
  • >> Review your results faster - The Impedance module with AxIS Z™ software provides a simplified approach to the setup, execution, and analysis of experiments.

Accurately evaluating cellular activity in vitro is essential for scientists and drug developers, but conventional endpoint assays can disturb the underlying biology or miss important events during cell proliferation, death, and signaling. With continuous, label-free, impedance-based monitoring of your cells in real time, Axion BioSystems’ next-generation Maestro TrayZ overcomes these limitations—providing a high-throughput platform to accelerate the development of urgently needed immunotherapies, ensure the quality of cell-based products, identify potential antivirals, and investigate other complex cellular behavior in vitro.

impedance technology

Impedance Technology Explained

Impedance-based cell analysis is a well-established technique for monitoring the presence, morphology, and behavior of cells in culture. Impedance describes the obstruction to alternating current flow. To measure impedance, small electrical currents are delivered to electrodes embedded in a cell culture substrate. When cells are present and attached to the substrate, they block these electrical currents and are detected as an increase in impedance.
