Contractility Safety Analysis

Our contractility safety analysis service offers a non-invasive in vitro assay to measure true contractility of human cardiomyocytes with exceptional accuracy under physiological mechanical boundary conditions. In a customized assay format also co-cultures of the cardiomyocytes with hiPSC-derived cardiac fibroblasts can be applied.

The system provides an ideal tool to assess pharmacological, safety pharmacological and toxicological effects of drug candidates on human cardiomyocytes.

The only true force measurement
on the market at medium-throughput

Sensitive and predictive
for cardiac safety pharmacology


hiPSC-derived cardiomyocytes are cultured on plates featuring a flexible culture substrate composed of a ultra-thin silicone membrane. Together with these culture plates the custom made assay system allows for measurements and quantification of the contraction-induced deflection of the silicone membranes. This is facilitated by a combination of capacitive distance sensors and a pressure sensors beneath the membrane of each well. All measurements are performed in a cell culture incubator at 37°C and 5% CO2.
