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…

Single-Use Technologies and Other Key Drivers in Biomanufacturing
The biomanufacturing industry has issues. From key drivers and hurdles, to the spectre of leachables legislation and the need for greater harmonization between suppliers, the biotech sector is experiencing a period of growing competition and increasing pressure. But, it is also a market with a future; the commercial success of more than 350 approved biologics has prompted the biotechnology industry to accelerate discoveries in further protein-based therapeutics, placing greater emphasis upon the importance of biomanufacturing. In addition,…
Supplier Innovation is an Imperative
As organizations begin their annual budgeting meetings, the question will inevitably arise: How can we reduce costs and still retain or improve our quality? For some, the answer to the first part may seem easy, but to have a packaged improvement plan that includes both aspects appears to be more indefinable. So what can the biopharm industry do to counter these daily pressures? The answer may not be as elusive as you think. Companies need to drive innovation…
A Readily Available Source of BSA Consistently Supports Cultivation and Differential Gene Expression
Lyme disease caused by the spirochete Borrelia burgdorferi is the leading vector-borne illness in the United States (1). The natural infectious lifecycle of B. burgdorferi is complex in that it is necessary for the bacteria to colonize both an arthropod vector (the Ixodes scapularis tick, pictured right) and a mammalian host (2). As the bacteria transitions between those two diverse niches, it alters the expression of its major outer surface proteins (Osps) such that expression of those that…
Managing Solid Waste from Single-Use Systems in Biopharmaceutical Manufacturing
The increasing implementation of single-use systems (SUS) in biopharmaceutical manufacturing has been driven by multiple factors including cost reduction, increased flexibility, improved process development time, and reduced capital investment. But questions are being raised over the disposal of solid waste materials from this alternative technology. Disposal concerns may not be justified on financial considerations because solid-waste disposal costs represent only a small proportion of the total manufacturing costs when using disposable systems (1, 2). Furthermore, comparative studies have…
Quality Assessment in 3D Cultures of Disc-Chondrocytes
Autologous chondrocyte transplantation is a modern experimental therapy for treatment of degenerative intervertebral disc diseases. Several studies with animal models have shown that transplantation of cultivated autologous chondrocytes can delay progression of disc degeneration. A few products based on human autologous chondrocytes are already on the market. Repair of disc damages with grafted chondrocytes appears feasible in the near future. So chances are growing for clinical applications meant for restoration of original disc function. As a result, optimization and standardization…
Applying Good Engineering Practices to the Design of Single-Use Systems
Significant changes are being incorporated into biopharmaceutical manufacturing processes as a result of drivers such as increasingly strict regulatory demands, reduction of manufacturing costs, and outsourcing to contract manufacturing organizations (CMOs). Historically, many biopharmaceutical processes were designed and built based on cleanable, reusable stainless steel systems and unit operations. Today several industry drivers are shifting some unit operations toward single-use technologies, namely lowered cross-contamination, reduced capital investments, and desired further reduction in manufacturing costs and shortened drug development times (1,2,3).…
TFF Membranes for High MAb Concentration
In a typical monoclonal antibody (MAb) purification process, immediately after cell culture and supernatant clarification (its objective being to remove whole cells, cell debris, and particulates), the protein product is typically bound to an affinity chromatography resin and then recovered by elution using a buffer solution. Once recovered, the resulting protein solution is further purified through additional chromatography and virus clearance steps before being concentrated until a final solution is ready for filling and finishing operations. PRODUCT FOCUS: MONOCLONAL ANTIBODIESPROCESS…
Technologies and Training Move Sterility to New Levels
Take six people and sample the microbial ecosystem on their forearms, and you will find more than 240 distinct microbes (1, 2). So it becomes readily apparent why keeping a cleanroom “clean” is a difficult task. One problem is that we humans are limited in our visual capacities and can see objects down to only 50 µm (3). If we could see contaminating particles, we would likely be very quick to clean them away. In fact, cleaning and cleaning validation…
CMOs Can Add Value to Outsourced Projects
Organizations outsource tasks to contract service providers for diverse reasons ranging from internal resource constraints (particularly in virtual or start-up companies) to overflow capacity, or to avoid or delay capital or resource investment. The scope of outsourced work varies from limited tasks such as an outsourced assay to complete process development and GMP manufacturing. In a highly competitive outsourcing market, customers expect successful and timely execution of the outsourced work, but they also seek “added value” to the overall program.…
