DNase footprinting assay is a molecular biology technique used to identify the specific binding sites of proteins, such as transcription factors, on DNA. The method takes advantage of the fact that when a protein binds to DNA, it can protect the bound region from being digested by deoxyribonuclease (DNase) enzymes.
