Qp binds STAT-4. (A) Electrophoretic mobility-shift assay showing binding of purified STAT-4 to Qp probe (lane 2). The DNA–protein complex was disrupted by anti-STAT-4 antibody (lane 3) but not by control antibody (lane 4). (B) Electrophoretic mobility-shift assay illustrating the specificity of STAT-4 binding. STAT-4 binding was competed by unlabeled STAT-4 (lane 3), Qp (lane 4), and QpIRFmAT (lane 6) oligonucleotides but not by QpSTAT mutant (lane 5) or control oligonucleotides (lane 7). Lane 1 contains Qp probe alone.
