Request Information

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-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.

Key Features

 

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.

 

What is MEA?

 

muliwell MEA system cell culture steps

 

MEA means microelectrode array and is a method of recording activity from electrically active cells, such as neurons or cardiomyocytes.  Axion’s microelectrode array (MEA) plates have a grid of tightly spaced electrodes embedded in the culture surface of each well (Figure A). Electrically active cells, such as neurons or cardiomyocytes, can be cultured over the electrodes (Figure B). Over time, as the cultures become established, they form cohesive networks and present an electrophysiological profile (Figure D). The resulting electrical activity, spontaneous or induced firing of neurons, or the uniform beat of cardiomyocytes, is captured from each electrode on a microsecond timescale providing both temporally and spatially precise data.

 

...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.

 

What is impedance?

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. The opposition to current flow from one electrode to another defines the impedance of the cell-electrode interface. When cells are present and attached to the substrate, they block these electrical currents and are detected as an increase in impedance.

 

Impedance live cell analysis steps for TEER and virology

 

Axion's 96-well CytoView-Z plate has a recording electrode embedded in the culture surface of each well (Figure D). The Maestro Pro system uses impedance measurements (ohms, Ω) to quantify the presence of cells on the electrode. To measure impedance, small electrical signals are delivered to the electrodes (Figure E). Cell attachment, spreading, and cell-cell connections block these electrical signals and are detected as an increase in impedance (Figure F). Impedance is also sensitive to subtle changes in cell conformation, such as those caused by receptor-mediated signaling or cell morphology. Since impedance is non-invasive and label-free, impedance assays can be used to quantify dynamic cellular responses over minutes, hours, and days.

 

The complete platform

 

 

  • 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 cells 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 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-, 24-, 48-, or 96-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 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.
