WebMar 9, 2024 · DNA Footprinting. Studying DNA–protein interactions is an important aspect of molecular biology. Researches use a variety of methods to study these like the chromatin immunoprecipitation (ChIP) assay, …
A DNase footprinting assay is a DNA footprinting technique from molecular biology/biochemistry that detects DNA-protein interaction using the fact that a protein bound to DNA will often protect that DNA from enzymatic cleavage. This makes it possible to locate a protein binding site on a particular DNA molecule. The method uses an enzyme, deoxyribonuclease (DNase, for short), to cut the radioactively end-labeled DNA, followed by gel electrophoresis to detect the resulting cle… Webthis video describes how DNA footprinting assay could be a good assay to detect dna protein interaction About Press Copyright Contact us Creators Advertise Developers …
WebThe gel-shift assay cannot identify the position at which the protein binds along the DNA. Furthermore, this assay cannot be used to determine whether the shifted band is caused by two proteins binding to two different sites on the same DNA fragment. The DNA footprinting technique addresses these limitations of gel-shift assay.
