TCDD-inducible and concentration-dependent DNA binding at Prdm1 promoter MARE. (A) Electrophoretic mobility shift assay performed on naive and LPS-activated (10 μg/ml) B cells treated with TCDD (10 nM) or DMSO (0.02%) for 0 or 4 h. The 0 h indicates background binding in untreated B cells. (B) Electrophoretic mobility shift assay performed on LPS-activated (10 μg/ml) B cells treated with the indicated concentrations of TCDD or 0.02% DMSO for 4 h. In both assays, binding reactions were set up with 32P-labeled promoter MARE probe as described in experimental methods. The arrow head indicates the TCDD-inducible DNA-protein complex. Results are representative of three separate experiments.
