Perfusion Media Exchange Strategies: Reducing Shear Stress and Maximizing Output

Perfusion Media Exchange Strategies: Reducing Shear Stress and Maximizing Output Introduction Effective media exchange is one of the most important parameters in a perfusion bioreactor, yet many teams overlook its impact on productivity, viability, and long-term stability. Since perfusion maintains cells in their exponential growth phase, the media exchange strategy determines nutrient availability, waste removal, and overall … Continue reading Perfusion Media Exchange Strategies: Reducing Shear Stress and Maximizing Output

Reducing Lactate Accumulation for More Efficient Protein Production

Reducing Lactate Accumulation for More Efficient Protein Production Introduction Lactate buildup is one of the most common bottlenecks in high-density mammalian cell culture. Moderate levels may be tolerated, yet sustained accumulation reduces viability, depresses productivity, and complicates purification. With targeted control strategies, you can steer metabolism, stabilize pH, and raise titer without adding complexity. Why … Continue reading Reducing Lactate Accumulation for More Efficient Protein Production

Osmolality Control: A Practical Lever for Higher Titer and Better Quality

Osmolality Control: A Practical Lever for Higher Titer and Better Quality Small shifts in osmolality reshape cell physiology, metabolism, and protein quality. By tracking and steering osmolality through the life of a culture, teams can improve titer while maintaining consistent glycosylation and viability. This practical guide explains why osmolality matters, how to measure it accurately, … Continue reading Osmolality Control: A Practical Lever for Higher Titer and Better Quality
