Intensified CMC Significantly Brings Titer Improvement

Robust and efficient production processes are crucial to the success of IND-Enabling studies and to the preservation of product competitiveness. GenScript ProBio's ‘Time & Quality-Balanced’ process development strategy, including using cell pool samples for purification preliminary development and cell culture process optimization, 3L samples for purification process optimization and formulation development, and 10/50L samples for process scale-up and purification process lock greatly shortens the process development timeline.

GenScript ProBio has developed a mature antibody purification platform process that allows clients to quickly establish a production process with an overall recovery rate of around 70% and with acceptable product characteristics, process and product-related impurities. GenScript ProBio will customize the processes to meet the unique needs of each client. For example , in the case of biosimilars, GenScript ProBio has effective techniques and tools to change the distribution of product glycoforms and charge isomers. In the case of recombinant protein with low stability, GenScript ProBio has developed different DoE tool boxes to ensure the titer and yield.
