Cardio.Force Service

The Cardio.Force Service offers a non-invasive in vitro assay to measure true contractility of human cardiac myocytes with exceptional accuracy under physiological mechanical boundary conditions. The standard assay service is based on Ncardia’s proprietary Cor.4CE® system, and uses monolayers of Cor.4U® human cardiomyocytes. In a customized assay format also vCor.4U® or co-cultures of the cardiomyocytes with hiPSC-derived FibroCor.4U® cardiac fibroblasts can be applied.

The combination of Cor.4U® with the Cor.4CE® system is the first in vitro assay setup to measure true contractile force of iPSC-derived cardiomyocytes in a system compatible with medium throughput. The system provides an ideal tool to assess pharmacological, safety pharmacological and toxicological effects of drug candidates on human cardiomyocytes.
