DNase I footprinting titration experiments. The 81bp DNA fragment containing A5 and ATATA sites was incubated with increasing concentrations of DB75, DB766, DB1876 and DB1880 as indicated on the top of the lanes (μM) prior to be subjected to DNase I mild digestion. A) The digested products were separated on a 8% polyacrylamide gel containing 8M urea. Sequences at the footprinting sites are indicated to the right of the gel. B) Corresponding densitometric analysis reveals the localization of the footprints (black boxes) along the DNA sequence.
