Recombinant blood group antigens are useful for studying the fine specificity of antibodies against glycophorin A encoded antigens.
Recombinant wild-type and variant forms of glycophorin A (GPA) were expressed in wild-type and glycosylation-defective Chinese hamster ovary cells. The binding to recombinant GPA of antibodies submitted to the Third International Workshop was assessed by immunoprecipitation and indirect immunofluorescence. This is a powerful approach for determining the fine specificity of antibodies to blood group antigens. The advantages and limitations of this approach are discussed.
