University of British Columbia and Centre for Blood Research have created an enzyme that can transform all donated blood into a universal type that can be given to any patient. The enzyme works by snipping off the sugars, also known as antigens, found in Type A and Type B blood, making it more like Type O. Type O blood is known as the universal donor and can be given to patients of all blood types. “The concept is not new but until now we needed so much of the enzyme to make it work that it was impractical,” says Steve Withers, a professor in the Department of Chemistry. “Now I’m confident that we can take this a whole lot further.” The study was published in the Journal of the American Chemical Society and was supported by the Canadian Institutes of Health Research and Canadian Blood Services.
