DQw3 (DQw7, DQw8, DQw9): 2-D Gel Patterns

DQw3 polymorphism has been described previously at the serologic, biochemical, and genomic level (1–8). In the present study, HLA class II α and β chain polymorphism was investigated by two-dimensional (2-D) gel electrophoresis of immunoprecipitated molecules in a panel of 27 HLA-DQw3 lymphoblastoid cell lines (Table 1).
