EMSAs performed on MG63 nuclear protein extract and on SW1353 nuclear protein extract using increasing concentrations of the YY1 consensus sequence unlabeled competitor probe. C and A correspond to the fluorescently labeled −41bp C-allele and A-allele probes used, respectively. YY1 Comp represents the unlabeled YY1 consensus sequence competitor probe added at 5 × , 10 × and 50 × relative to the C-allele and A-allele probes. Arrows depict the location of a protein:DNA complex whose intensity clearly diminishes as more competitor is added.
