Quantitation of HLA antigens on red cells by immunoradiometric assay.
Immunoradiometric assay was employed to quantitate HLA antigens on red cells. Using this technique HLA-B7, HLA-B17 and HLA-A28 were detected on the red cells of all individuals studied irrespective of the serological status of the Bennett-Goodspeed (Bg) antigens. However, HLA antigenic sites for serologically Bg positive red cells were significantly more than that for Bg negative red cells (P less than 0.001). Bga positive red cells possessed maximum number of antigenic sites as compared to Bgb and Bgc positive red cells.
