WebThe Rh (rhesus) system was first recognized in 1939 and defined as D in 1940. The antibody produced by guinea pigs and rabbits in response to rhesus monkey cells agglutinated 85% of human RBCs. This was called anti-Rhesus, and the corresponding human antigen was called Rhesus. It is now known that Rh is not identical to D. WebRh antigens, also called Rhesus antigens, are transmembrane proteins expressed at the surface of erythrocytes. They appear to be used for the transport of CO 2 and/or ammonia across the plasma membrane. RBCs that are Rh positive express the one designated D (RhD antigen). About 15% of the population have no RhD antigens and thus are “Rh negative.”
