WebFeb 16, 2024 · A short DNA fragment bearing the G-box motif in the PhGA20ox3 promoter served as a probe for electrophoretic mobility shift assay (EMSA). The results revealed a clear binding of PhOBF1 to the biotin-labeled probe, whereas the binding was dramatically suppressed when the unlabeled probe was added ( Fig. 7A ). WebThe filter binding assay can also be used to assess these assumptions, with some caveats. To determine the stoichiometry, comparable concentrations of RNA and protein are used; usually the [32 P]-RNA has a lower specific activity for these measurements.
