Promocell supplies high-quality hepatocytes and specialised media for in vitro research. The cells are isolated from the normal liver tissue of single donors and are immediately cryopreserved under controlled conditions to achieve maximum cell viability. The company tests its hepatocytes extensively for viability, Phase I and Phase II metabolism, albumin synthesis, and high adherence. They are optimally suited for in vitro applications such as toxicology testing or metabolic assays.
