QPS-Hepatic Biosciences is the world leader in producing, characterizing and qualifying human and animal hepatocytes from surgically discarded healthy tissues and whole liver organs rejected for transplant. With over 30 years of hepatic and extra-hepatic liver cell isolation, culture and assay experience we have found that tissue sourcing and organ preparation are critical components to producing cells that are of the highest quality possible. Our long standing and global tissue procurement program is second to none and has proved instrumental in the return to high quality hepatocytes of year's past. Over the last 5 years the research community has been very vocal about ever declining quality of hepatocyte preparations as traditional vendors have sought to lower the quality bar, sell less than suitable cells and increase profits at the expense of research. At QPS Hepatic Biosciences, we will never claim that every batch of hepatocytes we produce are of equal quality but we will recommend cells that work best for your applications and research goals through our own experience in using these same cells for our sponsored studies. Our primary objective is to extend the utility, increase the availability and to set a new global standard for top quality hepatocytes. Our aforementioned tissue procurement programs, state of the art analytical groups, our innovative isolation processes, new recovery and culturing protocols and an unparalleled scientific expertise all contribute to our mission and success.
