Vendor Voice: A New Paradigm for Bacterial Strain Engineering

From rapidly obtaining sufficient amounts of active protein in early stage development to cost effectively producing kilogram and even metric ton quantities for commercial supply, protein expression is critical at every stage of biopharmaceutical drug development. Having a high-performance protein expression platform across all stages is invaluable for the speed and success of protein and vaccine development. Historically, biopharmaceutical researchers and process development scientists have used Escherichia coli in their laboratories to generate small quantities of protein. If target expression…

Carbohydrates and Their Analysis, Part Three

A large proportion of the therapeutic biotechnology products already in the market or under development are glycoproteins. Therapeutic glycoproteins are produced as recombinant products in cell culture systems, which raises the importance of understanding the biosynthetic events described in the previous installments of this three-part article. Lack of control in a bioprocess could easily change glycosylation patterns by distorting the activities taking place in the Golgi apparatus. Disruption of the delicate balance among substrate availability, optimum pH for specific activities,…

Reviewing the Real Costs of GMP Compliance

Readers of our February 2008 article “Construction and Start-Up Costs for Biomanufacturing Plants: Canadian Case Studies in the Cost of Regulatory Compliance” may have noticed something missing (1). Two somethings, in fact: First, biographical information for coauthor Agnès Coquet was not listed at the end of the article. She is manager of analytical development for Debiovision Inc. of Montreal, Quebec, in Canada; 1-514-842-9976, ext. 104; acoquet@debiopharm. ca. Second, “Table 1” was called out on the fourth page of the article…

It’s Not Whether but Rather What and How to Implement

When considering integration of single-use technologies (SUTs or disposables) into a manufacturing process and facility, a number of criteria should be satisfied. These criteria govern both selection and implementation. Each criterion should be established by due diligence in which end-user requirements and the operation setting are considered carefully. Depending on a facility’s infrastructure and even a company’s business model, end users will define their criteria differently. Companies are driven to single-use technologies because of the simplicity and flexibility they impart…

Complete BPSA Component Quality Test Matrices

LUIS CARLOS TORRES (WWW.ISTOCKPHOTO.COM) As one of its first initiatives, the BPSA Technology Committee conducted an initial review of referenced quality test methods and specifications currently applied to common components of single-use systems: filter capsules, films and containers, tubing, and connectors and fittings. Recognition of consensus quality test methods, referenced to established industry standards and regulatory bodies, can help guide users when making their selections and can facilitate qualification, validation, and use of single-use products. Ultimately they can serve to…

Single-Use Applications for Biopharmaceutical Manufacturing

As single-use products are increasingly implemented, end-users are exploring applications, designing system approaches, assessing suitability and economics, and demanding expanded capabilities. Industry experts say that the single-use market is now moving into its next phase in which suppliers and developers are being challenged to not only “step up” and offer larger scale options, but also to provide additional downstream capabilities. IBC’s 5th International Single-Use Applications for Biopharmaceutical Manufacturing conference will provide over two days of current knowledge and strategies to…
