title: Analysis of the HLA-A10-crossreacting group of antigens by one-dimensional isoelectric focusing.
abstract: The antigens belonging to the HLA-A10 group, HLA-A25, -A26, -Aw34, and -Aw66, have been characterized serologically during the International Histocompatibility Workshops. However, it remains difficult to discriminate between the HLA-A26 antigen on the one hand and the HLA-Aw34 and -Aw66 antigens on the other on the basis of serology. In this paper, we compare the serologically defined antigens with the data obtained by one-dimensional isoelectric focusing. The results indicate that the serologically well-defined HLA-A25 antigen cannot be discriminated from the HLA-A26 antigen by one-dimensional isoelectric focusing. In contrast, this technique can indeed be used to discriminate between HLA-A26, -Aw34 and -Aw66 antigens. In addition, the biochemical analysis suggests further heterogeneity of the HLA-Aw34 antigen. This antigen can be subdivided into three variants.
