Single-Use Bioreactors and Microcarriers

Cell-based therapies hold promise for treating many acute and chronic diseases (1). Optimism surrounding that therapeutic potential has driven the initiation of multiple clinical trials in pursuit of such treatments. Procedures for preparing these therapeutic agents begin with selective isolation of cells from desired tissues. That is followed by ex vivo expansion of cells of desired phenotype and functionality. Once expanded to acceptable levels, cells are stored to preserve their viability during transportation to treatment facilities. The final step in…

Analytics for Modern Bioprocess Development

Twelve years ago, about the same time the US Food and Drug Administration was putting the finishing touches on its quality by design (QbD) and process analytical technology (PAT) guidelines, I wrote an article about breakthrough pharmaceutical educational programs. That article included the perspectives from a few members in academia of the future essential skills for pharmaceutical students. At the time, bioinformatics and computerized industrial process modeling were relatively new disciplines, but their importance in future manufacturing was clear. Several…

Powders and Bulk Liquids

    The two major bioprocess fluids — culture media for upstream production and buffers for downstream processing — are classic single-use products. They are used once and then disposed of. The two basic options for both differ by physical state: powdered media and buffers (“powders†for in-house preparation of liquids by end users) and bulk liquid culture media and buffers, which are fully prepared by their suppliers (“liquidsâ€). We conducted market research studies comparing the benefits and risks (value…

Bioprocess Advances Drive Vaccine Manufacturing in Developing Countries

Advances in bioprocessing technology hardware and genetic engineering are expanding the geographic options for biologics manufacturing to include developing and emerging economies. Such advances are beginning to permit biopharmaceutical production in regions that previously lacked the technical expertise or quality processes to permit complex operations, monitoring, record-keeping, and oversight. Global demand by countries for in-country production of biological vaccines is increasing, so those products tend to be leading the way in terms of adoption of modern bioprocessing in developing countries.…

North, South, East, and West

Electrophoresis is the basis of all blotting methods, and BPI Lab covered it last month (1). Electroblotting is a method for transferring electrophoretically separated proteins or nucleic acids onto a polyvinylidene fluoride (PVDF) or nitrocellulose membrane for permanence using electric current and a transfer buffer solution. This allows for analysts to further study them using probes, ligands, or stains. Capillary blotting is a variation designed to work with capillary electrophoresis. After electrophoresis the following are stacked in cathode-to-anode order: a…

Nucleic Acid Impurity Reduction in Viral Vaccine Manufacturing

Commercial-scale viral vaccine manufacturing requires production of large quantities of virus as an antigenic source. To deliver those quantities, a number of systems are used for viral replication based on mammalian, avian, or insect cells. To overcome the inherent limitations in production outputs with serial propagation of cells, mammalian cells can be immortalized, which increases the number of times they can divide in culture. Modifications that immortalize cells are typically accomplished through mechanisms similar to those converting normal cells to…

Evolving Biologics Demand Spurs New Facility Needs

In the era of biologics manufacturing, chemical medicine production facilities are becoming the dinosaurs of the life sciences sector. Traditional chemical facility development and management systems are simply unequipped to support the highly sensitive — and highly regulated — process of developing and producing biological and biosimilar medicines. Renovating or building such facilities anew is a mammoth undertaking by any measure. All signs point to the value of evolving facility design and management to house more sophisticated biologic laboratory services.…

Enabling Technologies

Many technological advancements in recent years have enabled companies to shorten time to market, to better understand their manufacturing processes, and to characterize their products well. In BPI’s December 2013 issue (pages 47–50), I reported on the first half of an informal reader survey about those technologies, with commentary from some survey participants and others. This month concludes with my examination of analytical, formulation/fill–finish, and facilities technologies. Analytical Technologies After writing several installments of our new “BPI Lab” series this…

Innovation in Biopharmaceutical Manufacture

The following is a report from a workshop on innovation in biopharmaceutical manufacturing held at the Annual bioProcessUK Conference in Bristol on 29 November 2012. The aim of the workshop was to access the experience of practitioners in the United Kingdom so as to understand better the challenges and opportunities for innovation in this sector. The workshop addressed the drivers that influence the implementation of process improvements and novel technologies in biopharmaceutical manufacture from the perspective of both manufacturers and…

Optimizing for the Future

The 2013 biennial meeting of the European Society for Animal Cell Technology (ESACT) was in Lille, France this past June. While there, BPI editorial advisor Miriam Monge (vice president of Biopharm Services Ltd.) interviewed ESACT executive committee member Hitto Kaufmann, PhD (vice president of biopharmaceutical process sciences for Boehringer Ingelheim). They talked about some scientific developments being discussed at this year’s ESACT conference as well as Boehringer Ingelheim’s recent announcement about setting up in China and Kaufmann’s own thoughts on…
