Recombinant Protein Expression in the Pharmaceutical Industry: Success in CHO

Life Sciences, Pharmaceutical, Drug Discovery & Development, Biosimilars,
  • Tuesday, April 19, 2022

This webinar will focus on the use of the Chinese Hamster Ovary (CHO) system in the pharmaceutical industry. The CHO expression system is the most frequently used non-human mammalian cell line for developing and generating biological therapeutics. The CHO system is favored for its resilience to variations in growth conditions and resistance to infections. They can be grown to high densities making it possible to obtain recombinant protein expression at high yields.

In this webinar, the featured speaker will detail the differences between commonly used protein expression systems. In addition, attendees will learn why the CHO platform is preferred in drug discovery. This webinar will also be open to questions to discuss any other topics of interest related to this CHO platform.
