DR5 (DRw11, DRw12): 2-D Gel Patterns

HLA-DR5 was subdivided after the 9th Workshop into two specificities, HLA-DRw11 and HLA-DRwl2 (1). Despite some discussion in the 10th Workshop (2), it was finally agreed to retain both DRw11 and DRw12 as splits of DR5(3). The biochemical characteristics of the class II molecules expressed by the DRwll and DRwl2 cell lines are described in this report.
