A STUDY OF THE DISTRIBUTION OF INCOMPLETE RHESUS ANTIBODIES AMONG THE SERUM IMMUNOGLOBULIN FRACTIONS
Sera containing Rh antibodies were taken from Rh-negative women at intervals during pregnancy and postpartum. A selection of these was fractionated on DEAE cellulose and by density gradient ultracentrifugation. The distribution among the immunoglobulin fractions γ(SS), γ(1)A, and γ(1)M of Rh antibod...

| Sumario: | Sera containing Rh antibodies were taken from Rh-negative women at intervals during pregnancy and postpartum. A selection of these was fractionated on DEAE cellulose and by density gradient ultracentrifugation. The distribution among the immunoglobulin fractions γ(SS), γ(1)A, and γ(1)M of Rh antibodies in the sera of Rh-negative women during pregnancy was analysed by these fractionation procedures and also by treatment with 2-mercaptoethanol and by testing with rabbit antisera prepared against purified immunoglobulin fractions. The experiments showed that incomplete Rh antibodies occurred in the 7(SS)-, γ(1)A-, and γ(1)M-globulin fractions, although the bulk of the antibody was in the 7(SS). In addition, evidence that the previously described (13) "papain-type" antibody is an incomplete γ(1)M-globulin is presented. |
