Use of a recombinant deacetylase to convert A1 red blood cells to the acquired B phenotype for quality control purposes
Background - Correct blood group typing is the cornerstone of transfusion medicine. In patients whose gastrointestinal wall is compromised, bacterial enzymes can cause deacetylation of blood group A, converting N-acetylgalactosamine to galactosamine, which resembles the B-defining galactose. This acquired B (acqB) phenomenon, first described 1959, can lead to blood grouping errors. Herein, we expl
