Electrophoretic mobility shift assay analysis of nuclear NF-κB protein from peripheral blood mononuclear cells. Lanes 1 and 10, controls; lanes 2 to 8, 17 and 18, steroid-resistant systemic lupus erythematosus (SLE) patients; lanes 9 and 11 to 16, steroid-sensitive SLE patients. Nuclear NF-κB protein levels were quantitated by density-analysis software.
