Assume you have identified a presumptive zinc finger motif through sequence comparison. Assume you have also found a gene that seems to be regulated by a protein that contains this presumptive zinc finger motif. But you do not yet have any evidence that this newly identified motif actually binds DNA. How would you like to investigate whether the protein containing this motif is indeed capable of interacting with a DNA fragment? How would you determine the Kd of the binding reaction?
