Maestro Edge

Axion BioSystems Maestro Edge

Maestro Edge

Maestro Edge™ multiwell microelectrode array (MEA) system is a versatile multimodal MEA and impedance system with 6-, 24-, and 96-well* throughput. ​

The Maestro Edge noninvasively evaluates cellular function in an easy-to-use in vitro assay. Whether monitoring the intricate, electrical activity of excitable cells (e.g., neurons and cardiomyocytes), or tracking the growth and death of cancer cells, Maestro Edge provides high quality, functional data to accelerate your research.​

*96-well only available for impedance.

Key Features



  • >> Measure cellular activity label-free and real-time — The Maestro Edge detects key parameters of neural network activity, cardiac functionality, and cell growth, death and attachment.
  • >> Precisely control the cells environment — Cells are a product of their environment. Maestro Edge has a smart environmental chamber that finely controls temperature and CO₂ while rejecting electrical noise and mechanical vibrations.
  • >> Connect to your network — 384 simultaneous live recordings from your cells with the Neural and Cardiac modules. Now you can understand life’s circuitry label free in real time in 6- or 24-well plates.
  • >> Continuous cell monitoring — 96 simultaneous live recordings from your cells with the Impedance module. Track cell proliferation, morphology, and viability in real time.
  • >> See your cells — Sometimes you just want to look at your cells under a microscope. Maestro’s CytoView™ patented transparent circuit technology allows cell visualization and assay multiplexing.
  • >> Control cellular activity — Recreate specific patterns of cellular activity using electrical stimulation or light pluses (with the Lumos optical stimulation system).
  • >> Start your assay with the push of a button — "One button setup,” means temperature and CO₂ levels automatically adjust on plate docking. Plate usage is logged via an integrated plate barcode scanner for convenient experiment tracking.
  • >> Monitor the kinetics of your biology on your smartphone — No need to be in lab. With the Impedance module, track changes in cell proliferation, viability, and cell killing over minutes or weeks.


5 star review

Easy to use and reliable

"MEA systems are becoming a gold standard tool for functional assays especially in the field of using stem cells for disease modeling and potentially drug screening and discovery. During my PhD and now at industrial level, we get very high quality data with MEA systems which is reproducible and consistent with the literature. Unlike patch clamping, it is very useful in studying network functions of the cultures. In addition, it is very user friendly, the sales support is great."

Electrical activity can give important context to your research. Detailed functional characterization is critical for understanding disease mechanisms, but many researchers avoid it because the techniques can be laborious. Electrophysiology doesn’t have to be difficult. The Maestro MEA platform makes it easy to perform complex electrophysiological experiments and gain deep insights into the function of cells. But the Maestro Edge isn’t just an MEA system — it also features sensitive impedance-measuring capabilities to monitor the kinetics of cellular growth, death, and signaling in real time. ​

Since launching our first multiwell plate-based Maestro MEA system more than a decade ago, it has become an indispensable tool in academic, biotech, and pharma labs around the world. 

Maestro Edge platform and compatibility with peripherals, plates, and assay types



MEA and impedance software


The Maestro Edge platform is available with six software modules: Neural, Cardiac, MEA Viability, MEA Automation, Impedance, and GxP Impedance. Select the software modules to match your assay needs:

Neural – Measure the key parameters of neural network function, including activity (are the neurons functional?), synchrony (are the synapses functional?), and oscillation (is the network functional?).

Cardiac – Record the four key measures of functional cardiac performance, label free and in real time in every well of the multiwell plate: action potential (a.k.a. LEAP assay); field potential; propagation; and contractility.

MEA Viability – Measure cell viability and coverage on MEA plates for a complete structure-function assay.

MEA Automation – Automate Cardiac and Neural MEA assays with this API for interfacing with liquid handling platforms.

Impedance – Track cell proliferation, morphology, and viability label-free and in real-time. Ideal for immuno-oncology, cytotoxicity, virology, cell migration, cell proliferation, GPCR assays, and many more.

GxP Impedance – Achieve FDA 21 CFR Part 11 compliance in GMP/GLP labs with this version of the Impedance Software Module.
