Rockville, Maryland’s Fina Biosolutions recently was awarded an SBIR grant to develop a genetically detoxified tetanus toxin as a carrier protein for conjugate vaccines. The NIAID funded grant is for $289,000 and will use a mutant toxin engineered by Dr. Joseph Barbieri of the Medical College of Wisconsin. FinaBio’s Scientific Director, Andrew Lees, noted “We are very appreciative of the help from BHI in securing this grant which will help us to commercialize a new genetically detoxified vaccine carrier protein that complements our existing conjugate vaccine portfolio.” FinaBio has created an E. coli strain with an oxidative intracellular environment that grows to very high densities and can express soluble disulfide bonded proteins. The mutant tetanus toxin will be produced in this E. coli strain and compared as vaccine carrier protein with the chemically detoxified protein.
