We Finally Have Found a Way to Convert Donor Blood Into a Universal Type

Science Alert  June 12, 2019
Researchers have known that certain enzymes could remove the sugars from A, B, and AB blood cells, converting them into the more useful Type O. Among the genes encoded in their library of 19,500 expressed fosmids bearing gut bacterial DNA, researchers in Canada identified an enzyme pair that work in concert to efficiently convert the A antigen to the H antigen of O type blood 30 times more efficiently than any previously discovered enzyme. The next step would then be to test the enzyme in a clinical setting, which will help determine if the conversion process produces any unintended consequences…read more. TECHNICAL ARTICLE
