Antigen Description and Distribution The Rh D antigen (Rh1 or Rho) is clinically the most important of the Rh blood group system. It is expressed on the extracellular loops of a transmembrane polypeptide of around Mr 300001. In humans the Rh D antigen is expressed solely on the erythrocytes of Rh D positive individuals. 85% of Caucasians are Rh D positive. Clone The cell line producing RUM 1 is a human heterohybridoma derived from the fusion of EBV transformed B cells, from the peripheral blood of a donor producing high levels of anti-D, with X63Ag8.653 myeloma cells2. RUM 1 reacts as a direct agglutinin with all Rh D positive red cells except those of DVI type confirming the designated epitope as epD6/7h3,4,5. RUM 1 reacts with HMi, HMii, DFR, DBT and RoHAr Rh D types3. RUM 1 (code I-103) was submitted to the third international workshop on monoclonal antibodies against human red cells, Nantes 19966. RUM 1 can be used as a reagent both for manual tests and in automated cell groupers for the reliable detection of Du7. References 1. Cartron, J-P, (1994) Blood Reviews 8, 199-212. 2.
