what is a radioligand binding assay?
<answer> They 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. <context> 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.
