Cor.4U®  
Cardiomyocytes

Cor.4U® Cardiomyocyte Kits are developed and manufactured for use in drug discovery and development and general cardiovascular research. The kits include either  1 vial (>1M/>4M cells/vial) cryopreserved cells, or 1 flask (0.5M/1M/3M)  seeded human Cor.4U® Cardiomyocytes, and 1 bottle Cor.4U® Complete Culture Medium (250 mL). 

 

Product Information

Pre-clinical studies of drug effects using human induced pluripotent stem cell (hiPSC)-derived cardiomyocytes provide novel possibilities for the assessment of efficient and reliable safety and efficacy drug screening that translate to clinics. Cor.4U® Cardiomyocytes are fully functional hiPSC-derived cardiomyocytes obtained through in vitro differentiation of transgenic hiPSCs and puromycin selection technology for the resulting cardiomyocytes. 

Product Data

Product Specifications

Cor.4U® Cardiomyocytes are a mixture of different subtypes of cardiomyocytes (60% ventricular, 30% atrial and 10% sinodal) differentiated from human-induced pluripotent stem cells. Ncardia’s proprietary technology ensures 100% purity of Cor.4U® cardiomyocytes using puromycin selection driven by a tissue specific promoter (cardiac aMHC).

First contractions of Cor.4U® Cardiomyocytes appear between 24 - 48 hours post thawing. It will take 3 days before the cells have formed a complete, electrically coupled monolayer. Stable beating monolayers can be observed 3 days post-thawing (50 - 120 BPM). The optimal time window to perform electrophysiology-based assays with Cor.4U® Cardiomyocytes is between 3 - 14 days after plating the cardiomyocytes, though this does vary by assay.
