Environmental scanning is the term used to describe the acquisition and use of information gleaned from sources external to your company. Scanning can be thought of as a form of early-warning radar that lets managers look into the future.
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.
