Average Rating 4.7

Application Area:

Cellular Electrophysiology

・Very intuitive and easy to use. ・The reproducibility of the test was high, and it was confirmed that there was no difference between facilities. ・The price was a little high due to the exchange rate, but I am very satisfied with the quality of the product.

Review Date: 8 Jun 2023 | Axion BioSystems

Overall enjoy the data that comes from the axion


Average Rating 4.3

Application Area:

Analyze electrical activity of primary neurons in disordered states

Overall enjoy the axion maestro system, obtained the plexon spike sorting software to also extract the spike waveforms. Some of the protocols lack description and would benefit to be more descriptive. Neural metric analysis tool a little limited in terms of information output.

Has its strengths and weaknesses, use with caution


Average Rating 4.0

Application Area:

Organoid research

Mostly a very useful device for 2D electrophysiology, and has some uses for 3D cultures. It’s biggest strength is that it will automatically pump out more metrics than you can use, which can be great for an in-depth look at bigger networks. Unfortunately, there can often be noisy electrodes out of the box, and electrodes can grow more noisy over longer term cultures. Additionally, neurons will continuously grow and migrate away from the electrode grid if the whole well is coated with a positively charged amino acid, which will undoubtedly muddy results. Be careful to only coat the electrode grid and seed appropriately. Overall, it provides a means to look at network physiology without the need for patching, viral transduction, or dyes.

Analysis needs tweaking


Average Rating 3.7

Application Area:

Motor neuron signaling

I think the software for analysis is quite confusing and could use a more user friendly interface because it isn't obvious where to click for what analysis.

Smart instrument with professional after-sales service.


Average Rating 5.0

Application Area:

iPSC derived neural cells, 3D organoids, toxicology, drug screening

I have used the MEA system for more than 5 years, in both the UK and China. Maestro MEA is an easy-to-use compact system. It provides a straightforward solution that always gives high-quality and reliable results. Most importantly, the Maestro MEA system keeps developing, which helps customers to extend the research fields they use it for continuously. Now, Maestro has been incorporated into my research, not only for central neural cells, but also peripheral neural cells, as well as organoids. It will be even more great if Maestro MEA software can be improved by equipping more customized functions.

The Maestro Pro™ multiwell microelectrode array (MEA) and impedance system is our most advanced offering, designed for the workload of larger labs. Record from our 6-, 24-, 48-, and 96-well MEA plates, and 96- and 384-well impedance plates.

Maestro Pro allows for non-invasive evaluation of your cells 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 Pro allows you to investigate the functionality of your cells in a multiwell plate.


  • Measure cellular activity label-free and real-time - The Maestro Pro detects key parameters of neural network activity, cardiac functionality, and cell growth, death, and attachment.
  • Precisely control the cell's environment - Cells are a product of their environment. Maestro Pro has a smart environmental chamber that finely controls temperature and CO₂ while rejecting electrical noise and mechanical vibrations.
  • Connect to your network - 768 electrodes simultaneously record from your cells with the Neural, Cardiac, and MEA Viability modules. Now you can understand life’s circuitry label-free and in real time in 6-, 24-, 48- or 96-well plates.
  • Continuous cell monitoring - 384 simultaneous live recordings from your cells with the Impedance module. Track cell proliferation, morphology, and viability in real-time in 96- or 384-well plates.
  • 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 pulses (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.

The complete multiwell MEA system

The evaluation of electrically-active cells has historically been tedious, requiring months of training to painstakingly study single cells in low throughputs. By culturing a network of cells over the high electrode count arrays available in each well of our MEA plates, Axion BioSystems’ Maestro Pro multiwell MEA system captures activity across an entire population of cells, with far greater data points per well, detecting activity patterns that would otherwise elude traditional assays. Axion’s contribution to establishing microelectrode array (MEA) technology as an accessible, versatile research tool cannot be defined by a single advantage. It’s the cumulative effect of our commitment to growing our multiwell MEA system to include instruments, accessories and software working in unison.

...and impedance system, all in one platform

Cell-based assays enable rapid evaluation of human biology in vitro, with substantial advantages in throughput and cost over tissue or animal models. However, many cell-based assays are endpoint assays, limited to a single snapshot in time. Axion BioSystems’ Maestro Pro platform also offers impedance-based cell analysis for real-time, continuous, label-free monitoring of your cells. Continuous data reveals the kinetics of cell-cell interactions and cell-drug responses for better mechanistic understanding without the time- and cost-intensive process of repeating multiple endpoint assays.
