Abstract:
Decoupling upstream and downstream operations in biopharmaceutical production could enable more flexible manufacturing operations and could allow companies to leverage strategic or financial benefits that would be otherwise unattainable. A decoupling process was developed and scaled up utilizing single-pass tangential flow filtration for volume reduction, followed by bulk freezing in single-use bags prior to purification. Single-pass tangential flow filtration can be used to continuously concentrate harvested cell culture fluid, reducing the volume by 15-25× with a step yield of >96%. These concentration factors were reproduced with a second product, indicating that the process could be amenable to platform processes. Experimental data indicate that the product tested was stable for at least one year at -40 or -70°C. The concentration of the harvested cell culture fluid-either with or without a subsequent period of frozen storage-had no impact on the product quality attributes that were tested. © 2018 American Institute of Chemical Engineers Biotechnol.
