Transporter Certified Hepatocytes

Current Promotions

Select lots of Sekisui XenoTech cryoplateable human hepatocytes have been certified by a 3rd party* to culture for 5 days and maintain both uptake and efflux transporters as well as proper bile canaliculi formation. The transporter-certified hepatocytes have passed a multi-point evaluation starting with plating/culturing characteristics and ending with a broad evaluation of hepatic functions including uptake and efflux transporter functions, metabolic function and baseline bile acid synthesis/production. Each lot of certified hepatocytes contains the following information:
