"For the first time, the new enzyme cocktails not only remove the well-described A and B antigens, but also extended variants previously not recognized as problematic for transfusion safety. We are close to being able to produce universal blood from group B donors, while there is still work to be done to convert the more complex group A blood. Our focus is now to investigate in detail if there are additional obstacles and how we can improve our enzymes to reach the ultimate goal of universal blood production," says Professor Maher Abou Hachem, who is the study leader at DTU and one of the senior scientists behind the discovery.
Cinemax's excellent 'The Knick' (about a chief surgeon at the Knickerbocker Hospital in 1900's New York) had a gut-wrenching one or two episode arc about efforts to refine transfusion techniques and why the team kept seemingly randomly ending up w/dead patients because no one had yet understood Rhesus factor proteins.
