Erythrocytes have significant value in specific types of research. If your objective is biobanking these cells in an intact state then it is equally important that hemolysis and the need for a re-draw is avoided. This paper explains how hemolysis can be prevented during specimen collection and handling.
Large molecules require special handling procedures for bulk drug substance, formulation, and sterile filtering and filling of the final drug product, forcing change on many levels of the manufacturing process.
Downstream processes for biomolecule purification are becoming more complex. Challenges include increasing titers from upstream cell culture, greater diversity of target molecules, and a need for better productivity. HIC has characteristics designed to solve these challenges. In this study, the hydrophobicities of newer generation Capto HIC resins were compared to Sepharose High Performance and Sepharose Fast Flow HIC resins.
The transfer of mAb production processes between scales, referred to as scale-up or scale-down, is difficult. This study reviews moving mAb production from a microscale bioreactor to a single-use platform.
This paper includes a discussion on vaccine processes, followed by a case study on the scale-up of upstream and downstream processes for the production of a cell-based live attenuated influenza virus using single-use ReadyToProcess technology.
