ADDITIONAL GENE-CONTROLLED ANTIGENIC FACTORS IN THE BOVINE ERYTHROCYTE

Abstract

N PREVIOUS reports from this laboratory evidence has been presented for I the existence of 30 gene-controlled antigenic factors in the erythrocytes of cattle Each of these 30 antigens of cattle in contrast to its absence has behaved as a dominant character, as do the known antigenic components of blood cells in other species. None of the 30 factors are necessary alternatives as are the M and N agglutinogens of human cells Evidence for antibodies which detect additional antigenic variation in the erythrocytes of cattle is given in this report. Attention was previously called to the associations of certain of these antigenic factors with others These relationships are somewhat comparable to the relationships of the so-called subtypes A1 and A2 of the A agglutinogen of man. A system of designating serological subtypes of certain of these antigenic components is proposed.
