Contract for synthesis of complex brucella antigen carbohydrates

APHA has been working with organic chemists at the University of Alberta on research using synthetic sugars as antigens for brucella diagnostic tests. These antigens have great advantages over the existing antigens. Small research quantities of these complex sugars have been provided by the University. APHA has filed a patent on these sugars for use in diagnostic tests and vaccines. Small quantities have been provided to veterinary diagnostic companies who now require larger quantities to fully evaluate. APHA now needs to get a significant amount of these complex sugars synthesized to allow wider evaluation by diagnostic companies, sale of the antigen and the issuing of licenses for companies to use the sugars in their tests’.
