The PXB-Mouse is a chimeric mouse with a humanized liver that is highly repopulated by human hepatocytes. PXB-mice are utilized in the prediction of human Metabolic Profiles, Drug Induction/Inhibition, Human PK, Bile secretion, etc.PXB-cells are “fresh” hepatocytes taken directly from a PXB-Mouse liver, consisting of over 90% pure human hepatocytes. PXB-cells can be supplied from our large stock of PXB-mice (stable supply), which have hepatocytes from one donor (reproducibility), and can be prepared anytime you need (immediacy).
