Development and Optimization of CHOgro® Transient Expression Technologies for High Titer Antibody Production in Suspension CHO Cells

During early stage drug development, quickly obtaining relevant candidate proteins through transient transfection can accelerate drug dis-covery. High titers are often obtained from Human Embryonic Kidney (HEK) 293 derived cell types; however, the use of different host cells between early stage transient and later stable protein production is a concern and can lead to the advancement of false-positive candidates. Chinese hamster ovary (CHO) cells are a desirable target cell type due to growth characteristics and a history of regulatory approval;…

Maximize Protein Expression in CHO Suspension Cells

          Transient transfection in mammalian cell lines provides an avenue for researchers to bridge the development bottleneck and shorten the time to usable protein. The method also maintains post translational modifications crucial for biotherapeutic function. Chinese hamster ovary (CHO) suspension cells are especially suited for high-yield production of recombinant proteins, despite being refractory to commonly used transfection methods (e.g., 25-KDa linear PEI). Mirus Bio has developed a more effective alternative, the TransIT-PRO™ transfection kit. Using this…
