The xCELLigence System monitors cellular events in real time without the incorporation of labels. The System measures electrical impedance across interdigitated micro-electrodes integrated on the bottom of tissue culture E-Plates.

The impedance measurement provides quantitative information about the biological status of the cells, including cell number, viability, and morphology. A wide range of cell-based assays for both high throughput screening and research laboratory environments can be performed on the xCELLigence System.
