Essential
Buffer solutions are fundamental throughout biopharmaceutical production, from initial cell culture to final formulation. They maintain pH stability, which is crucial for the activity, stability and bioavailability of APIs and sensitive biomolecules.
As biopharmaceuticals become more targeted, selecting the right buffer – and a reliable manufacturing partner – is key to success.
Applications and Functions in the Production Process
Cell culture and upstream processing:
Buffers create optimal environments for cell growth and consistent biomolecule production by stabilising pH over time.
Downstream processing and purification:
Buffers are vital during protein separation, purification and filtration, supporting processes like chromatography, ultrafiltration and diafiltration.
Final formulation:
In the last stage, buffers stabilise the active ingredient, ensuring product efficacy and shelf life, especially for complex drugs like monoclonal antibodies.
Quality Assurance and Compliance
All buffer solutions are produced in EU-GMP-certified facilities in Hannover (Germany) under a manufacturing licence according to the German Medicines Act.
Each batch is fully traceable, documented and reviewed by a qualified person before release, ensuring compliance with regulatory and industry standards.
