Gel Retardation Assay (Molecular Biology). The gel retardation assay, also known as the bandshift assay or electrophoretic mobility shift assay (EMSA), is used to detect DNA-binding proteins in crude cell extracts and to study the binding activity of purified DNA-binding proteins. It is also applicable to the study of RNA-protein interactions. The basis of the assay is that protein-DNA complexes remain intact when gently fractionated by gel electrophoresis and migrate as distinct bands more slowly than the free DNA fragment.
