Clone selection techniques used for development of stable, high-expressing recombinant cell lines suitable for robust fed-batch cell culture processes are critical for biopharmaceutical manufacturing. Basal media screening, feed development and addition strategies, and fed-batch bioreactor performance are all intimately tied to overall performance of the clones during scale-up. Serious issues can arise if a high-quality clone is not established, such as low or unstable protein yield and ineffective use of costly resources.
