There are many techniques and strategies that you can use to identify a DNA-protein interaction (when the DNA fragment is known). Here are some pros and cons for each, to help you choose which is best for your situation.
1. Gel shift assay
How:
perform gel shift under stringent binding conditions (high [salt], low temperature)
Pros:
Cons:
2. Biochemical purification of binding proteins
