Whilst osmolality measurement is widely adopted for testing the media and buffers used in bioprocessing, this webinar covers other emerging applications where osmolality is used both as a process parameter that can be manipulated to increase productivity and as a predictor for titer and glucose consumption among other things. These applications add huge value both in mAb biologics and in cell and gene therapy development.

Maximising Product Titre By Strategic Control of

Osmolality in Mammalian Cell Bioprocesses

Prof. Michael Butler

Osmolality is a key process parameter in mammalian cell bioprocesses that affects both specific cell growth and specific cell productivity. Published data shows that hyperosmolality, used in a targeted way at particular stages of the biological production process, for certain cell types, can enhance final product yield significantly. This presentation will review the strategies that can be used to manipulate osmolality to increase production yields of monoclonal antibodies and other recombinant proteins.

Osmolality: A Predictor in Mammalian Cell Culture

Prof. Alois Jungbauer

We have explored the quality and significance of osmolality as a predictor for titer, glucose consumption, and growth-inhibitory by-products such as ammonium in mammalian cell culture. CHO cells were cultivated in 5-liter bioreactors in fed-batch mode expressing a recombinant antibody of the subclass IgG1. In addition to the conventional on-line and at-lien measurements, osmolality was measured at-line. The measurements of the different runs were used to establish correlations with osmolality and independent runs to test the predictive power of osmolality. Interestingly the osmolality is a good predictor for glucose, ammonium, and dissolved CO2 among others with a weaker power. The implementation of osmolality measurement and its application in bioprocessing will be discussed. 

Upstream Applications of Osmolality Testing in Cell & Gene Therapy Processes 

Kendal Studd

Osmolality can be used as a versatile, robust tool to help improve cell and gene therapies, adding a necessary and beneficial process parameter. The presentation will focus on the incorporation of osmolality testing into upstream applications which include media development, feeding strategies, and the minimisation of aggregation.
