title: Demonstration of gene dosage effects on antigens in the Duffy, Ss, and Rh systems using an enzyme-linked immunosorbent assay.
abstract: Using a recently developed enzyme-linked immunosorbent assay, gene dosage effects were demonstrated for the Duffy, Ss, and Rh red blood cell antigen systems. We report a comparison by an antibody-binding assay of the relative amounts of Fya and Fyb antigens on FyaFya, FyaFyb, FybFyb, FyaFyx, and FyxFyx erthrocytes, and of s antigen on cells homozygous and heterozygous for s. The immunosorbent assay also was used to study Rh antigens, and data which had been obtained using radiolabelled antibodies were confirmed.
