Anti‐Aub: The Antithetical Antibody to Anti‐Aua

Abstract
Anti‐Aub, the first example of the antithetical antibody to anti‐Aua, was identified in the serum of a blood donor who had been transfused 16 years previously. Aub has a gene frequency of 0.4326 in an American black population and 0.2994 in a southern English donor population. The expression of Aub is suppressed by In(Lu). XS2 also suppresses Auberger antigen expression.
