RALEIGH, NC – SEPTEMBER 8, 2010 – Ajinomoto Aminoscience LLC (AAS) today announced availability of a new whitepaper that outlines the common challenges associated with recombinant protein production and discusses how novel expression systems, such as the CorynexTM Recombinant Protein Expression System, are helping simplify the production process, reduce costs, and speed time to market.
Along with highlighting CorynexTM, the new whitepaper, entitled “Speeding and Simplifying Recombinant Protein Production,” also examines market drivers of recombinant protein production, challenges unique to each protein, benefits and drawbacks of expression systems (bacteria, yeast, and mammalian host cells), as well as key considerations and questions to ask when selecting a production process.
Recombinant protein technology provides a wealth of commercial opportunities. However, production is time-consuming, costly and subject to technical pitfalls. In addition, conventional microbe-based expression systems often use micro-organisms such as E. coli, pseudomonas and yeast, which require multiple purification steps, additional subsequent refolding and may contribute impurities. Traditionally, overcoming these challenges has meant refining or optimizing individual steps within the production process.
Ajinomoto’s CorynexTM Recombinant Protein Expression System uses a specially-developed gram-positive bacterium, Corynebacterium glutamicum. The expression system secretes correctly-folded, active proteins directly into the growth media with minimal host cell protein secretion and no endotoxins. By secreting active proteins directly into the growth media, Corynex eliminates the need for extensive downstream processing and additional refolding steps, which often result in 50% to 80% losses in target proteins.
In addition to developing the whitepaper, Ajinomoto has also created an educational video that uses computer-generated animation to illustrate protein expression in a way that’s never before been seen. The video provides an in-depth look at the expression and export of recombinant proteins from Corynebacterium glutamicum compared to E. coli and demonstrates how CorynexTM allows the recombinant protein to be readily purified directly from the fermentation broth.
