unlike rbc autoantibodies from antiglobulin-positive normal blood donors , autoantibodies from patients with autoimmune hemolytic anemia did not show rh-dependent properties as judged by antigen site density , absence of differential binding to rbc of different rh phenotypes , failure to immunoprecipitate 30 kd rh-epitope bearing membrane polypeptides , absence of multiple antibody populations , and the lack of a significant nonadsorbable igg population that has been associated with the presence of antiidiotypic igg .
