Upstream Processing

Concerns, Collaboration, and Capacity

The BPI Theater is a 50-seat venue that for seven years has been located at the heart of the BioProcess Zone on the exhibition floor of the BIO International Convention. There, BPI provides attendees with four days of live presentations focusing on the latest scientific advances and business trends in biotherapeutic development and manufacturing. On Monday afternoon, 22 April 2013, Patricia Seymour of BioProcess Technology Consultants (BPTC) moderated a roundtable discussion on biosimilar development in the BPI Theater at BIO…

Overview of a Scale-Up of a Cell-Based Influenza Virus Production Process

The aim of this white paper is to demonstrate how GE Healthcare Life Sciences single-use products can be applied in the field of vaccine manufacturing. A brief discussion around modern vaccine processes is followed by a case study showing the scale-up of upstream and downstream processes for the production of a cell based live attenuated influenza virus using single-use ReadyToProcess technology. Single-use equipment enables quick changeover between products, minimizes risk for cross-contamination between batches, and reduces the need for cleaning and validation operations.

Better Cells for Better Health

Since its inception 35 years ago, the biennial meeting of the European Society for Animal Cell Technology (ESACT) has built on a tradition of combining basic science and applications into industrial biotechnology to become the international reference event in its subject matter. Every other year, this gathering of academics and industry professionals features a famously exciting social program and an extensive vendor/supplier exhibition specific to animal cell technology. ESACT meetings are much-anticipated international venues for information exchange, inspiration, networking, and…

High-Throughput Chromatography Screenings for Modulating Charge-Related Isoform Patterns

Monoclonal antibodies (MAbs) are an important class of biopharmaceuticals and are widely used to treat a variety of diseases such as cardiovascular diseases, cancer, and blood disorders. Antibodies are very complex proteins that show a high degree of microheterogeneities, including charge-, hydrophobicity- and size-related variances (1). Such variants can arise during any stage in a manufacturing process or storage as a result of enzymatic or nonenzymatic processes (2). Particular antibody variants that may affect the in vitro and in vivo…

Broadening the Baseline

When the editors of BPI asked us at BPSA to put together a content-rich article on single-use issues, we were happy to do so. Our challenge was how to bring in multiple viewpoints about the growing business of single-use that would be a “quick read” for the BPI audience. The answer: an expert colloquy. Represented here are several of the most qualified industry spokespersons in single-use — all are members of BPSA and speak as directors of the alliance. Their…

Broadening the Baseline

When the editors of BPI asked us at BPSA to put together a content-rich article for the single-use supplement, we were happy to do so. Our challenge was how to bring in multiple viewpoints about the growing business of single-use that would be a “quick read” for the BPI audience. The answer: an expert colloquy (a “conversational exchange or topical dialogue”). Represented here are several of the most qualified industry spokespersons in single-use — all are members of BPSA and…

Development and Qualification of a Scalable, Disposable Bioreactor for GMP-Compliant Cell Culture

During the past decade, single-use bioreactors have become widely accepted for use in cell culture process development and clinical manufacturing. Their key benefits over stainless steel bioreactors are flexibility, cost, and time savings associated with the reduction of cross-contamination risks (1). Here, we describe our approach to development and qualification of the Biostat STR single-use, stirred-tank bioreactor. Unlike other stirred single-use bioreactors, it offers a similar design to that of well-established, conventional (stainless steel) stirred-tank bioreactors. Disposability of the single-use…

Amplifying the Possibilities

Polymerases are natural enzymes that are vital to nucleic acid synthesis: DNA polymerase for replication of deoxyribonucleic acid and RNA polymerase for replication of ribonucleic acid. Thus all living things make and use polymerases of their own. But in 1969, the University of Wisconsin’s Thomas D. Brock and Hudson Freeze identified a new species of extremophilic bacterium thriving at 160 °F (70 °C) in a hot spring in Yellowstone National Park. In time, heat-tolerant polymerase isolated from Thermus aquaticus (Taq)…

Single-Use Pumps Take Center Stage

The multibillion-dollar global biopharmaceutical industry is placing increased emphasis on development and manufacture of advanced biologics. Such products offer exciting potential for the development of drugs that could provide as-yet-unknown treatments for a wide array of diseases. One important goal is to commercialize biologic products as early as possible within the typical 20-year patent window. Patent submission must occur during drug development. Much work follows a patent filing, including further product development, toxicity checks, and clinical trials. Hopefully, US Food…

High-Yield Production of PASylated Human Growth Hormone Using Secretory E. coli Technology

Since the 1985 approval of the first recombinant human growth hormone (hGH, such as Protropin/somatrem human growth hormone from Genentech, now Roche), the number of clinical indications for therapy with hGH has steadily increased (1). That led to a highly successful drug with more than US$3 billion sales in 2011 (2). Even so, hGH shares a common problem with most other first-generation protein therapeutics: a very short plasma half-life of just about two hours in humans. Because such biologics are…
