title: Detection of two distinct public specificities on HLA-A28 bearing lymphocytes.
abstract: We have used the antiglobulin augmented cytotoxicity assay and platelet absorption-elution techniques to investigate crossreactivity among certain antigens coded by the HLA-A locus. These serologic and absorption studies demonstrated two supertypic determinants, distinct from private determinants, associated with HLA-A locus gene products. One determinant was present on HLA-A2, Aw23, Aw24, and A28 bearing lymphocytes; the other was found on HLA-A28, Aw33, Aw34, and A26 bearing lymphocytes. The second determinant was not associated with HLA-A25. Both supertypic determinants are associated with HLA-A28.
