Ripley-Like Serum and other Anti-Rh Sera in Detection of Fc Receptor-Bearing Human Lymphocytes

Abstract
Three anti-Rh sera useful for the EAhum [antibody-coated erythrocyte] test were found (1 comparable to Ripley serum). The usefulness of anti-Rh sera for the EAhum test depends on the amount of anti-Rh antibodies absorbed onto red cells demonstrated in the manual antiglobulin test. It does not depend on the quality of antibodies and the ability of complement binding.
