The Center for Integrated Biosystems (CIB) at Utah State University proposed to demonstrate the added benefits of bench top stirred-tank bioreactors utilizing the packedbed impeller system in perfusion mode for the production of recombinant proteins. In this study recombinant Chinese Hamster Ovary (CHO) cells were utilized for the production of a secreted protein in two bioreactor types: pitched-blade bioreactor operated in batch mode versus packed-bed bioreactor operated in perfusion mode. Our primary objective was to determine whether the packed-bed bioreactor is superior to a traditional pitched-blade bioreactor for the mass production of cell culture protein products. We hypothesize that the …

Influenza viruses cause between 3 and 5 million cases of respiratory infection each year and are responsible for between 250 and 500 thousand deaths. Two avenues for the treatment and prevention of influenza virus infections are vaccination and antiviral chemotherapy. Prevention is largely accomplished through vaccination. While vaccines remain the preferred method for controlling the spread of influenza, antiviral treatment is important for severe infections caused by new and emerging virus strains. Occasionally new viruses emerge to which the population has no previous immunity. Such was the case when the pandemic H1N1 influenza virus appeared in 2009. When new viruses …
