Antigen Society #24 Report (DRw11, DRwl2, DRw8)

Groups of sera defining a DR5 specificity correlated with HLA-Dw5 were first observed in the Seventh Workshop. However, sera of excellent quality recognizing a distinct DR5 antigen have been rare. In the Ninth Workshop, it was discovered that most DR5 sera contained antibodies against related DQ-specificities, and shorter patterns (DRw 11 and DRw 12) were defined.
