High-Performance for Large-Scale Products

      Recent advances in the research of therapeutic biologics have resulted in increased market demand for novel manufacturing systems to help meet the growing production need. Recent data resulting from increased research into the human immune system has resulted in the development of innovative treatments for a number of diseases with large unmet need both as vaccination and therapy. To compliment this growth, new approaches in pharmaceutical manufacturing help to fill complex biological products, not only to secure…

BioXcellence BI-HEX® Mammalian Expression Platform

    Figure 1: ()   The production of therapeutic proteins like monoclonal antibodies (MAbs) and bispecifics depends on mammalian expression due to the posttranslational modifications occurring in these molecules. At Boehringer-Ingelheims (BIs) BioXcellence unit, we use the BI-HEX™ mammalian expression platform for fast and cost-efficient development of high-titered manufacturing processes. The BI-HEX™ platform is composed of the following interlinked elements: BI’s proprietary vector system, the BI-HEX™ cell lines, which are derived from the CHO-DG44 cell line (1), a short…

Scale Up on Efficiency in Biologics Contract Manufacturing

      Wacker Biotech is a dedicated contract manufacturer of biopharmaceuticals with more than 20 years of experience in microbial systems. We offer proprietary technologies (ESETEC®, DENSETEC®) that significantly lower the cost of goods. Our customers benefit from a comprehensive service for the development of robust and highly efficient processes and GMP-compliant manufacturing for clinical trials and commercial supply. We opened recently a new process-development unit to optimize the entire process-development chain, from gene to purified protein. A second…

Scalability of Mobius® CellReady Stirred-Tank Bioreactors

      EMD Millipore has developed a family of single-use bioprocess containers designed for mammalian cell growth and recombinant protein production. The Mobius® CellReady product offering includes bench-scale (3-L), small-scale (50-L) and pilot-scale (200-L) bioreactors spanning early process development through clinical batch production. To enable the successful scale-up of a biomanufacturing process, a number of factors critical to efficient cell growth, viability, and protein production were considered and used to develop an optimized design. These include mixing efficiency, gas…

SoloHill Microcarriers in a 25-L PadReactor™ Single-Use Bioreactor

        The purpose of this study was to demonstrate compatibility and performance of SoloHill’s Collagen-coated microcarriers in ATMI Lifesciences’ Integrity™ PadReactor™ system. The solid polystyrene core of the collagen microcarriers prevents absorption of serum or cell products into the core of the microcarrier, and the 1.03 specific gravity and 125- to 212-μm diameter allows them to be maintained in suspension with gentle low stirring speed. These solid microcarriers provide an excellent substrate for cell growth. They can…

Filterability of Virus Stocks

Small-pore, virus-retentive nanofilters are designed to remove even tiny viruses from a biological product intermediate as it flows through the filter membrane. During process development, manufacturers carefully optimize filtration conditions to maximize product throughput so that at manufacturing scale, the number and size of these expensive virus filters can be minimized. During the viral clearance study, an attempt is made to filter a targeted volume based on preceding process development studies. If the filter’s pores become plugged with impurities from…

CHO Cell Culture

      Packed-bed basket technology developed by New Brunswick Scientific (acquired by Eppendorf Inc. in 2007) provides a shear-free environment for production of animal cells. Because little information is available on the utility of the New Brunswick CelliGen BLU single-use bioreactor system for production of secreted proteins (especially in perfusion mode), this study was conducted to measure growth and productivity of alkaline phosphatase (ALKP)–secreting rCHO cells. We used two packed-bed bioreactor types — a 5-L New Brunswick CelliGen BLU…

New EXP-Pak™ Closed-System Disposable Cell Expansion Bags

      Clinical cellular therapy applications often times require a cell expansion or maturation step before use. Traditionally, cell expansion or cell culture is performed in “open” systems including multiwell culture dishes or tissue culture flasks. These “open” steps present risks and are not ideal for larger-scale manufacturing. The new EXP-Pak™ cell expansion container is a closed-system, gas permeable bag intended for expansion and culture of nonadherent cells. EXP-Pak™ bags are made from a unique polyolefin film that permits…
