Researchers from the University of British Columbia have figured out how to convert blood types A, B and AB into the universal Type O, which all patients can receive in a transfusion, regardless of their own blood type.
Blood types are differentiated by the kinds of sugar found on the surface of red blood cells. Type O has no sugars. Scientists had realized that some enzymes can remove the sugars from A, B and AB blood cells, turning them into Type O, but they hadn’t found an enzyme that was safe, efficient and economical, until they considered the gut.
The scientists were able to isolate the enzyme and use it to strip blood of its sugars in a more efficient way than any other enzyme.
