Axion BioSystems’ Maestro ZHT™ platform measures cell proliferation, death, morphology, attachment, and signaling label-free and in real-time. Screen drug and biological candidates in 384- and 96-well plate formats. Track immune cell-mediated killing, viral infectivity, cancer cell invasiveness, endothelial barrier function, wound healing, and more.
These high-throughput assays are real-time, continuous, and label-free, revealing the full cellular response profile and kinetics using electrical impedance. Get more complete data without the time- and cost-intensive process of repeating multiple endpoint assays.
KEY FEATURES
Taking care of the assay so you can focus on the science:
- High-throughput, continuous monitoring of your cells — Up to 384 simultaneous live recordings from your cells. The Maestro ZHT system performs noninvasive electrical measurements from the cultured cell population, circumventing the use of dyes/reporters that can perturb your cells and confound results. Track activity over hours, days, and weeks from the same population of cells label-free and in real-time.
- Precisely control the cell environment — There is no need for an additional cell culture incubator, saving valuable lab space and money. Maestro Z’s smart environmental chamber finely controls temperature and CO₂ while rejecting electrical noise and mechanical vibrations.
- 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.
- Review your results faster — The Impedance module with AxIS Z software provides a simplified approach to the setup, execution, and analysis of experiments.
- 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.
- Achieve 21 CFR Part 11 compliance in GLP/GMP labs — Designed with clinical translation and a regulatory environment in mind, the optional GxP Impedance Module makes the assay easy to validate and fully auditable while maintaining many of the streamlined and user-friendly features of AxIS Z.
- Validate your assay for high-throughput screening — A 384-well cytotoxicity assay using the Maestro ZHT was validated for high-throughput screening, achieving high Z' (Z'=0.81, n=2) with no edge effects.
- Monitor your experiments from outside the lab — The Maestro Z App allows you to check in on your cells and experiment to ensure everything is running smoothly while you are away from the lab.
- Increase throughput with multiple Maestros — Simultaneously monitor multiple plates automatically with multiple Maestro support. Save space in your lab by controlling multiple Maestro systems using a single computer.

Maestro ZHT, high-throughput cell proliferation, morphology, and viability assays in real-time
This product brochure describes the technology behind Axion Biosystems Maestro ZHT cell-based assay instrument and some examples of its applications.
Validation of an impedance-based cytotoxicity assay for high-throughput screening
In this application note, a high-throughput screening (HTS) cytotoxicity assay was validated using the Maestro ZHT platform. The Maestro ZHT platform performs cell-based assays in 96-and 384-well plate formats. Using label-free impedance technology, cell viability may be monitored continuously over time within the Maestro ZHT under integrated environmental control. The validation study results support an impedance-based cytotoxicity assay with CytoView-Z 384-well plates on the Maestro ZHT for HTS applications.
TechTalk: Revealing deeper ADC cytotoxicity insights with live cell analysis for drug discovery
Friday, March 20 at 15:00 GMT | 16:00 CET | 11:00 EDT | 08:00 PDT
Antibody-drug conjugates (ADCs) require precise, reliable in vitro assays to understand potency, kinetics, and mechanism of action early in development. Traditional endpoint assays often miss critical dynamic responses and introduce variability through dyes and labels.
In this 20‑minute SelectScience® TechTalk, Field Application Scientist Viswanath Lanka will demonstrate how the Maestro Z™ label‑free monitoring system enables real‑time, impedance‑based assessment of ADC‑mediated cytotoxicity. See how continuous kinetic data reveals differences in killing dynamics, accelerates detection, and supports confident potency quantification.
