Evaluating New Film for Single-Use Bags: Growth Performance Studies with Animal and Human Cells

by , , , , , and

In biopharmaceutical development and manufacturing processes, single-use technology has become widely accepted (1). Storage and cultivation bags are particularly common. They are fabricated from plastics consisting of multilayer films and are typically provided gamma-sterilized by suppliers (2). The bags offer several advantages such as savings in time and cost. Lowered contamination risk results from reduced cleaning and sterilization demands. However, some adverse effects of polymer films on cell growth and metabolism have been reported, both for storage and cultivation bags…

Consistently Superior Cell Growth: Achieved with New Polyethylene Film Formulation

by , , , , , and

During the past decade, single-use bioprocessing bags and bioreactors have gained a significant foothold in the biopharmaceutical industry because they offer a number of advantages over traditional stainless steel equipment, especially for clinical production, multiproduct facilities, and emerging economies. At the same time, some companies are concerned that plastic materials might release potentially toxic substances that could affect cell growth and product titers (1). In a worst-case scenario, they could even compromise drug safety when a company uses disposable bags…
