When it comes to process development and manufacturing of protein therapeutics, whether you’re making an antibody-based or other protein therapeutic, what you don’t know can slow you down.
With the innovative osmometers from Advanced Instruments, you can gain valuable data for managing process and product quality through a simple 90-second test. Osmolality, the measurement of total solute concentration, is a reliable control specification and in-process parameter that can deliver information across the protein therapeutic process development and manufacturing workflow.
Optimize cell culture conditions to maximize cell density and yield.
Monitor buffer composition and processes, such as chromatography and filtration, to ensure protein purity and yield.
Monitor and verify the concentration of API and excipients to meet internal quality and regulatory requirements
When the therapeutic you’re developing is cell-based, constant monitoring to optimize growth and ensure consistent culture conditions throughout multiple stages is critical for success.
Using osmolality can help your group answer these questions early in the process, ultimately helping you save time, money, and limited or costly reagents. Adding a simple 90-second osmolality measurement to the in-process parameters you measure is a quick and easy way to ensure optimal cell growth, during process development and manufacturing as well as during buffer and media preparation.
With the innovative osmometers from Advanced Instruments, you can keep delicate cells at optimal growth and gain valuable data for managing process and product quality across the cell therapy process development and manufacturing workflow.

Osmolality testing has unlimited applications in areas of personal care and hygiene. Products that come into contact with or penetrate the skin must have an osmolality within a physiological range to avoid damaging cells and tissues. In some instances, slightly hypo- or hyper-osmotic solutions are generated to promote wetting or drying effects. The manufacturing of skincare products, personal lubricants and optical products
One key to a youthful look is healthy and moisturized skin. Proper hydration of skin depends on a balance of water flow into and out of skin cells and, thus, depends on osmolality. Osmolality testing of skincare products provides assurance that the product will have moisturizing effects and serves as a control during the production process.
The osmolality of personal lubricant formulations impacts their effect and safety. The World Health Organization (WHO) stated that the osmolality of these solutions should not exceed 1200 mOsm/kg, with this limit decreasing to a more iso-osmotic level in the future.
Similar value for osmolality testing can be clearly seen in optical applications. Eye drops and other optical products are designed to lubricate or protect the eye. The goal of these solutions (e.g. adding moisture, removing moisture, etc.) dictates an ideal osmolality range.
Osmolality testing is required to ensure that the final vaccine product is safe for administration. The osmolality must be within a physiological range to be introduced in human tissues. There is also evidence that injectable formulations with high osmolality may cause pain at the site of injection.
Vaccines are derived from a variety of sources, both living and synthetic, meaning a variety of bioproduction workflows are required. These workflows include some common use cases for osmolality testing, including the following:
Differentiation in use cases for osmolality testing are outlined below:
Monoclonal Antibody Vaccines
Osmolality testing should be performed on hybridoma cell media to ensure optimal antibody production rates.
Viral Vaccines
Osmolality testing should be performed on media solutions to optimize cell size and viral vector stability.
mRNA and DNA Vaccines
Delivery systems and mechanisms should be tested for osmolality.
COVID-19 vaccine development often falls into these development categories. To better understand how osmolality testing benefits the production of therapies, visit the respective tabs: Protein Therapies, Cell Therapies, Gene Therapies, Oligonucleotides.
An example of an accelerated mRNA vaccine production workflow is below:
This novel field involves the use of antisense oligonucleotides (ASOs), aptamers, siRNAs, miRNAs and synthetic mRNAs to control the expression of genes that have been associated with diseases. Multiple Advanced Instruments customers within this field use osmometers to verify the concentration of the solutions carrying their precious products. Ultimately, the quality of the drug is dependent on the process controls implemented throughout the workflow. Below are some of the current uses for osmolality testing in this field:
Osmolality specifications for buffers to preserve and protect the critical quality attributes of the product as it is being developed.
Compendial release test needed to confirm the identity and concentration of the oligo product for safe use.
Because this is an emerging field, it comes with a number of development and application challenges:
Drug delivery into the target cells requires the proper osmotic pressure, similar to the parameters around viral transfection in vector development. The optimal osmolality of the delivery complex (e.g. mRNA:PEI) should be determined and monitored during this process. This specification will provide repeatable successful delivery of the drug.
