Using Enzymes to Create Universal Donor Blood From Other Blood Types

Blood banks around the world always need type O blood, since it can be universally administered in an emergency. Now, scientists say they have identified enzymes originating in the human gut that can turn type A and B blood into type O blood by removing A or B antigens. These newly identified enzymes make the conversion into type O blood as much as 30 times more efficiently than previously studied enzymes.
