LifeTECH Abstract on Viral Inactivation in Human Red Blood Cells to be Presented at Experimental Biology '97 Conference TORONTO, April 8 1997 - LifeTECH Corporation today announced the acceptance of a scientific abstract describing innovative viral inactivation in human red blood cells by the Sterinetics(TM) System. The abstract, entitled "Virus Inactivation in Human Red Blood Cells by Induced Oxidative Stress", will be presented at the Experimental Biology '97 conference to be held April 6-9, 1997 in New Orleans. Principal author of the abstract is LifeTECH scientist Dr. Lilian Lee. Walter J. Dermott, President & CEO, made the announcement, saying, "Our research dramatically advances the science of inactivating viruses in human red blood cells. The unique ability of the Sterinetics System to inactivate 6 logs/ml of Bovine Viral Diarrhea Virus (BVDV) in red blood cells once again raises the bar for the competition. Our scientists have also developed important new methods for quantifying viral inactivation, as well as identifying assays to validate red blood cell structure and function after controlled oxidative stress. The Sterinetics System continues to be the only viable sterilization technology that can make blood transfusions safer for all." The abstract, Number 341/2981, describes the inactivation of three key viruses in human red blood cells: Bovine Viral Diarrhea (BVDV), an enveloped virus which models the human Hepatitis C virus; Infectious Bovine Rhinotracheitis (IBR), a large enveloped herpes virus; and Bovine Adenovirus, a non-enveloped virus that causes respiratory diseases in humans and bovine species. Experimental Biology '97 is a biomedical scientific meeting coordinated by The American Physiology Society, the American Society for Investigative Pathology, the American Society for Nutritional Sciences and the American Association of Anatomists. More than 8,000 scientists are expected to attend the newest scientific concepts and experimental results from around the world.
