Ajinomoto Aminoscience LLC Builds Upon Success Expressing Complex Proteins with CorynexTM Expression System


8/23/2011 10:25:50 AM

RALEIGH, NC – August 23, 2011– Ajinomoto AminoScience LLC (http://www.ajiaminoscience.com/Default.aspx) (AAS) today announced the availability of a case study profiling how one global pharmaceutical company relied on its Corynex™Recombinant Protein Expression System (http://www.ajiaminoscience.com/products/branded_products/corynex.aspx) to express and purify proteins. This new case study further builds upon Ajinomoto’s proven success (http://www.corynex.com/pdfs/case_study_viable-protein-opps.pdf) expressing complex proteins with the Corynex™ Expression System.

Initially, the global pharma company had difficulty expressing and purifying a particularly difficult protein via traditional e-coli and yeast-based expression systems. Since the pharma company was only able to express misfolded forms and aggregates, they became interested in testing whether Ajinomoto’s proprietary Corynex™ Expression System (http://www.corynex.com) was capable of expressing the correctly folded protein that could then be purified. This system uses the gram-positive Corynebacterium glutamicum to express folded active proteins directly into media, thus reducing purification steps and potential difficulties, lowering costs, and increasing yield.

Ultimately, Ajinomoto was able to demonstrate that Corynex™ can express correctly folded protein directly into the broth, whereas the customer could not. In addition, Corynex™ enabled the optimization of expression levels of the correctly folded protein, resulting in a significant cost advantage for the customer.

With this most recent success, Ajinomoto added to its knowledge base by understanding which proteins (size, complexity, characteristics, and uses) the Corynex™ Expression System can or cannot successfully express and translocate into the broth. Ajinomoto’s cumulative knowledge creates the possibility of licensing opportunities for pharma companies looking to bring the Corynex™ Expression System in-house for the development of other proprietary proteins.

To read more about the successes the company has experienced using Ajinomoto’s Corynex™ (http://www.corynex.com) , including reduced contamination, faster production times, as well as lessons learned from non-expressed proteins, please visit www.corynex.com . In addition to the case study, you can also download a related whitepaper, “Speeding and Simplifying Recombinant Protein Production” and view video animation of the expression and export of recombinant proteins from Corynebacterium glutamicum.
