Enabling Greater Process Control and Higher Protein Titers: Advances in Downstream Single-Use Technologies

Today, we feature an article from our partners at BioProcess International Magazine. This is an excerpt from the article Enabling Greater Process Control and Higher Protein Titers: Advances in Downstream Single-Use Technologies.

Downstream protein purification (the stage in which a protein is isolated and purified) is one of the last steps in biotherapeutic manufacturing. Single-use technologies are an increasingly popular choice for both upstream and downstream bioprocessing because they offer significant benefits over traditional multiuse manufacturing systems. Single-use technologies also provide an array of logistical benefits, including reduced costs, minimized risk of cross-contamination, and improved operational efficiency.

Challenges remain, however, in designing a complete, streamlined, single-use process for downstream protein purification. In-process sensor technologies, chromatography, and temperature control are all areas that have been traditionally underserved by single-use technologies and represent “weak points” in the downstream process flow. Exacerbating the problem, most proteins are heat labile and sensitive to a large number of environmental conditions. Therefore, interruptions in the process and improper temperature management can increase aggregation (which can lead to unstable formulations) or even degradation and denaturation in worst cases.
