WebThe Kidd antigen system are proteins found in the Kidd's blood group, which act as antigens, i.e., they have the ability to produce antibodies under certain circumstances. The Jk antigen is found on a protein responsible for urea transport in the red blood cells and the kidney.[1] They are important in transfusion medicine. People with two Jk antigens, for instance, … WebAnti-Jk3 is seen in severe hemolytic transfusion reactions but not HDN. The other pathway to this phenotype is a JKnull In(Jk) suppressor in which the cells type negative for the antigens but can be found in trace amounts. These patients do not make anti-Jk3 and the cells are not lysed by 2M Urea. No diseases are associated with this phenotype. avalon cb
