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 reviews the strategies that can be used to manipulate osmolality to increase production yields of monoclonal antibodies and other recombinant proteins.

In this presentation we 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. The measurements of 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 is also discussed.

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

Osmolality serves as a key orthogonal property in downstream processing. This webinar will demonstrate the value of osmolality testing as a key process parameter in buffer preparation, purification, and filtration operations.

FDA warning letters due to incomplete data in the pharma and biotech industries can be prevented by ensuring the reliability of electronic records, a process known as Compliance with Data Integrity. 

Osmolality is a measure of solute concentration and an indication of the solution’s osmotic pressure (USP, EP). It provides the concentration of any solution and has several potential applications within cell and gene therapy development and manufacturing. Learn more about the role osmolality plays in viral vector stability.

Data is critical for operations within the pharmaceutical and life sciences industries, whether it is for compliance, operational excellence, reporting or development. Data integrity enables convenience and trustworthiness in all types of data generated in several areas across the workflow. As more people, systems and tools consume data, it becomes increasingly valuable because it can be translated into action to improve quality and performance while reducing costs and time to market. However, with additional systems and users comes a risk that, if not managed correctly, can compromise the integrity of data.

The bottleneck for real time control and real time release is lack of product-specific in-line sensors or fast at-line methods suitable for model-based prediction of process outcome. There are multiple sensor-based parameters that help monitor a purification process, but which ones serve as predictors for protein concentration?
