title: Complexity of the bovine MHC class-II specificity DW3 as defined by alloantisera.
abstract: Alloantisera related to the bovine major histocompatibility complex (MHC) class-II specificity Dw3 were investigated by cross-absorption experiments and by application of the monoclonal antibody-specific immobilization of lymphocyte antigen assay (MAILA). The absorption study revealed antibodies specific for an antigenic determinant shared by all Ds03 (Dw3)-positive animals, and several other antibody populations recognizing the locally defined specificities Ds10, Ds11 and Ds15, that are closely associated with Ds03. The results of the MAILA-assay indicate that the Ds03 specificity is probably encoded by DQ, whereas specificities Ds10 and Ds 11 are more closely associated with DR molecules. The data presented here provide the first evidence that bovine DR and DQ specificities can be identified separately by serological methods using alloimmune antisera.
