Message From Our CEO

CEO-HeadshotLadies and Gentlemen, it is my great privilege and pleasure to welcome you to our newly launched Ascendance Bio website. Our combination of the assets of Hepregen Corporation and the former ESI BIO Division of BioTime, Inc. is well underway. Explore this site-in-process and click to our Hepregen and ESI websites where you will find detailed information on all our products and services, and instructions for placing purchase orders.

During the transition to a fully integrated operation be assured that your favorite Hepregen® line of micropatterned HepatoPac® and HepatoMune® application-directed assay kits will be available along with all of the ESI BIO laboratory products that you value so highly for your stem cell-related research. In addition, our science team will continue to provide you with an expanding Solutions-via-Service™ capability.

We also invite you to watch this site to see how Ascendance Bio will be enhancing our capabilities to serve your needs in all areas of in vitro safety and toxicology testing, metabolite-related analysis, and pharmaceutical efficacy research. As the launch of this website corresponds to the opening of the 55th Annual Meeting of the Society of Toxicology, I am also pleased to let you know that we will soon be making available new products for safety testing that we hope will be of great value to our established customers and new customers alike.

To our existing customers, on behalf of all of us at Ascendance, I would like to offer my sincere thank you for your loyalty. We will continue to work harder than ever to improve every aspect of our product line and service offerings to you. Expect to see not only new products but updated versions of our current products becoming available later this year. To those of you who are thinking about trying our products or service offerings for the first time, we encourage you to give us a call.

Finally, because of the growth of our business, we are now able to offer you many of your favorite products at a lower price. Explore your needs with our science team and let us give you a quote now for a high value Ascendance solution.
