The ultimate goal of recombinant fermentation research is cost-effective production of desired proteins by maximizing volumetric productivity (to obtain the highest amount of protein in a given volume in the least amount of time). Bioprocessing for recombinant proteins using genetically modified organisms requires a stable, high-yielding recombinant culture, a highly productive fermentation process, and cost-effective recovery and purification procedures. Escherichia coli has been a widely used host for expression of recombinant proteins (1). Its advantages lie in the enormous data…

Pursuing Excellence
As new medicines, vaccines, biomaterials, and biofuels move through development, companies often face some of their toughest hurdles in moving from benchtop to production-scale processes. These are not only technological, but as technology advances it becomes more difficult to find experienced talent to make use of it. Some regional endeavors, such as the National Biomanufacturing Centre in the United Kingdom and the Massachusetts Biomanufacturing Center in the United States are pooling skills and resources to help companies…
TIDES
For 2009, TIDES renews its focus on science. The agenda was put together by leaders in oligonucleotide and peptide development and manufacturing. The result is a program with novel, in-depth scientific data in each presentation. The agenda once again includes comprehensive coverage of drug candidates in development; new strategies for formulation and delivery; and the latest in regulatory updates, quality initiatives, process and analytical development, and manufacturing. This allows you the opportunity to benchmark your progress against that of your…
Biologics New and Improving
By far the most successful applications of biotechnology have been in the medical field. The vaccine industry is undergoing a complete transformation thanks to biotechnology. And cutting-edge research is giving us whole new ideas about disease therapy using nucleic acids and regenerative medicine. Proteins and Other Therapeutics Cancer has been a primary target for many MAb “magic bullets” and a major research area for life scientists over the past quarter-century. Oncologists have identified ∼200 cancers that affect human beings, some…

The Vaccine Renaissance
The global vaccine industry has undergone a dramatic and well publicized rebirth. Near the end of the 20th century, it faced an uncertain future with increased pricing pressures and liability challenges for marketed vaccines. Many long-standing members of the industry chose to scale back their R&D efforts or abandon them altogether. Today, however, the landscape has changed. Because of a confluence of positive factors (advancements in science and technology, greater appreciation for the role of vaccines as antibiotic resistance increased,…
An Industry in Transition
As an industry, biopharmaceutical manufacturing is in transition and is facing challenges borne out of success. It was in the early 1980s that the first products were commercialized, namely the replacement hormones insulin and human growth hormone. The industry initially grew rapidly in the early ‘80s against a background of an immature supply industry: there were no large-scale columns (>10 cm diameter), column controllers, limited resin supplies and no established ultrafiltration technology. The position today is that the industry has…
Of Mice and Men…
Few US industries demonstrate preeminent creative and financial world leadership year in and year out, but we can think of two that look forward to continuing blockbusters that will provide mountains of new cash followed by consistent follow-on revenues. In both arenas, an idea is calculated to be something that people everywhere will want, so it is launched with a huge bolus of cash and a cash burn that almost takes its company to the brink. Both industries capitalize on…
Biopharmaceutical Processes: A Glance into the 21st Century
Biopharmaceutical drug products are not only well established but also contribute to a large degree to new drug entity filings. Currently approved biopharmaceuticals and proteins are now widely used to treat diseases as diverse as cancer, autoimmune disorders, myocardial infarction and various growth factor deficiencies. The unmet medical need can be so essential, such as a novel approach to cancer treatment, that biotech companies will choose to defer the optimal design of the production process to reduce the…
Environmental Impact of Single-Use and Reusable Bioprocess Systems
Bioprocess manufacturing systems have incorporated single-use/disposable components for more than 50 years and have demonstrated well-defined process benefits from their use (1,2,3,4,5,6). The environmental impact of single-use technologies, however, has been a major focus of attention only in recent years. This evolving interest has been driven by many factors including concerns over environmental change, emissions, and energy supplies; rapidly increasing costs and restrictions on waste disposal; greater recognition of the role of disposables in bioprocessing; and availability of…
