Our market leading GS Gene Expression System®track record now underpins dozens of commercially available products and hundreds of others in clinical trials.

Customer testimonials

This powerful GS platform enabled us to fast-track CMC development from stable cell line generation to non-GMP Tox material supply to GMP clinical manufacturing.

— Dr. Feng Hui, Chief Operation Officer, Junshi Biosciences, China. July 2020

I just wanted to send a specific note of thanks for your early support in getting us the Xceed system – it was truly a differentiator for the program.

— Prof. Trent Munro, Program Director, The University of Queensland, Australia. June 2020

GSv9™ Media and Feeds resulted in ~50% more antibody production. Its preparation demonstrated to be less time-consuming and labor intensive. The GSv9™ Media demonstrated a higher potential for prolonging cell culture for additional day(s).
