[Specificity of antibodies formed in people with Rh-negative blood in response to administration to antigens C(rh', Rh2) and Cw(rhwf, Rh8)].

Anti-C, -Ce, -CD sera and monoclonal anti-C-antibodies with red cells varying by Rh-phenotypes comprising antigen C(w) have been studied. Four Rh-negative volunteer donors were reimmunized with antigens C and C(w). As shown by reactions of anti-C-sera, monoclonal antibodies anti-C with C(w)-positive cells, results of immunisation of the Rh-negative donors with antigen C(w) of Rh system, red cels containing Rh antigen C(w) contain also factor rh(C).
