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…

An Emerging Star for Therapeutic and Catalytic Protein Production
Since the 1980s launch of the first recombinant-DNA–sourced protein insulin, the 1990s introduction of interferons and interleukins, and the first commercial approval of MAbs around the turn of the century, the therapeutic protein market has shown a very healthy growth of 15–19% (Figure 1). Between 1980 and 2004, about 300 antibodies and 400 other recombinant proteins entered clinical trials, totaling about 750 products (1). Figure 1: () A survey of biopharmaceutical production technologies in 2005 shows that Chinese hamster ovary…
Effect-Based Compliance
Regulatory compliance is a competitive team activity that creates real value reflected in the bottom-line accounting of company profitability. Champions earn freedom to operate for their companies; losers are enjoined, have products seized, and/or are prosecuted for their (mis)deeds. The players and fans use FDA form 483s and warning letters as metrics for measuring relative standing. The operational paradigm is that “employees” tend to define competitors in the context of a company’s market. In the regulatory game, competitors are less…
