Technology -  Cellular Impedance Explained

Label Free, Real-Time Method for Studying Cells  

Cellular impedance is a fast, non-invasive method for real-time live-cell analysiswithout the need for labels or staining. Unlike traditional assays, it continuously monitors cell behavior by measuring electrical impedance changes as cells interact with electrodes in the plate bottom.

With exceptional speed and temporal resolution, this technology captures key cell metrics—proliferation, adhesion, morphology, migration, and differentiation—over seconds to days. By eliminating endpoint limitations, it delivers dynamic, quantitative insights for more accurate and comprehensive cell analysis.
