Human monoclonal anti-D antibodies. I. Their production, serology, quantitation and potential use as blood grouping reagents.
Eight monoclonal IgG antibodies to the Rh antigen D, produced by Epstein-Barr virus transformed B-lymphoblastoid cell lines from two individuals, have been assessed for their suitability as blood grouping reagents. All showed similar specificity and agglutinated all red cells with partial D antigens tested except category DVI cells. They gave strong reactions with Du red cells in indirect antiglobulin tests, and they all gave good reactions with R1R1, R2R2 and R0r cells in manual tests using antiglobulin, enzyme or albumin methods. Initial studies showed that some of the monoclonal antibodies worked well at high dilutions on a Technicon Autogrouper 16C when used for routine D-typing of blood donors. Antibody production by the cell lines was stable for many months in continuous culture. These monoclonal antibodies may be useful diagnostic reagents.
