High throughput bioprocess development is essential for optimizing run parameters prior to scale-up. University College London’s Advanced Centre for Biochemical Engineering is harnessing the possibilities afforded by automation, using custom-built scripts and programs to make its liquid handling platforms accessible to inexperienced users.

Biomanufacturing requires careful separation of the molecule of interest from other cellular products to ensure the quality and stability of the final product. This is even more important for the manufacture of biotherapeutics, as the presence of unwanted molecules in pharmaceutical preparations can affect the efficacy and safety of biologically-derived drugs. FUJIFILM Diosynth Biotechnologies is using automated chromatography condition screening to generate more data in less time, helping to improve the performance of purification processes and accelerate biological drug manufacturing.

The biosimilars market is expanding rapidly as the patents expire for an increasing number of high profile biopharmaceutical agents.
