Radioligand Binding Assay. Radioligand binding assays are used to characterize the binding of a drug to its target receptor. They can provide information on the both the affinity and mode of interaction of the drug with its receptor.lternatively, the receptor density (Bmax) and Kd in the tissue can be obtained by using a saturation radioligand binding assay in which receptor binding is determined in the presence of increasing concentrations of the radioligand alone.
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.
