A Novel HEK293 Stable Cell Line Platform for Development and Manufacturing of Difficult-to-Express Proteins
Zhaopeng Li, Shuo Wang, Qiao Gao, Wenqing Ye, Sam Zhang

CHO cells have been widely utilized for recombinant protein expression with proven track record. However, complex modalities may encounter difficulties when expressing in CHO cells, resulting in low titer levels and truncation issues, most likely due to the impact of some CHO-specific host cell proteins, that compromise the quality and functionality of the protein products. We have developed a new HEK293 stable expression platform, which can eliminate or significantly alleviate truncation issues in expressing complex molecules while maintaining high titer levels. In addition, the corresponding human glycosylation and other humanized PTMs may drastically lower the risk of immunogenicity, elicited by Neu5Gc or alpha gal etc. This novel platform will enable more complex, difficult-to-express, emerging biotherapeutics to the clinical and commercial stages.
