The TheraPRO® CHO Media System, a GS CHO cell culture media system, has been launched by Lonza to simply processes and optimize productivity and protein quality when used with GS-CHO cell lines. The system was designed to support pharmaceutical and biotechnology companies manufacturing therapeutic proteins to further improve product quality while streamlining time-to-market. The company claims the chemically defined, animal component–free, two-part production system achieves high viable cell concentrations and more than 5g/L protein titer during a 15-day culture cycle.
