Osmolality is described as the measurement of the contribution of all the dissolved solutes to the osmotic pressure of a solution. In BioPharma, osmolality is usually used as a quality control checkpoint for cell culture media, formulation buffers or formulated drug products.


The Cell Technology Group at the National Institute for Bioprocessing Research and Training (NIBRT) focuses on the development of bioprocesses using mammalian cells for the production of recombinant proteins, monoclonal antibodies and viral vaccines. There is also a particular interest in the bioprocess conditions that can be used to control the biochemical structure and the post translational modifications of glycoproteins and hence the quality of biopharmaceuticals.

In this webinar, the featured speakers share how they use osmolality as a quality control tool, similar to the routine application in the biopharma industry. In addition, osmolality is applied as an experimental measurement to correlate with IgG production, nutrient depletion studies and bioprocessing applications.

This webinar will describe the impact of osmolality assessment in correlation with IgG production when examining the effect of plant protein hydrolysates as additives, in a media development project. When examining the effect of changing media composition on IgG glycosylation in this project, osmolality was tracked and correlated with growth and productivity. Osmolality measurements were utilised to correlate the suitability of culture conditions in ‘re-fed’ media vs. controls of complete media during the investigation into the recoverability of cells at various stages of nutrient depletion. These preliminary investigations are currently in the process of being scaled up to bioreactor level (bench scale) where osmolality validation will be used on samples collected at line process analytical technology (PAT) instrumentation development.

Discover how osmolality is utilized as a quality control tool in biopharmaceutical development, including its correlation with IgG production and nutrient depletion studies, in this informative webinar.
