Maximizing Protein Expression in CHO Suspension Cells Through Transient Transfection

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. 25kDa linear PEI). Mirus Bio has developed a more effective alternative, the TransIT-PRO® Transfection Kit. Transfection efficiencies are affected by many…
