How do radioligand assays work
WebCompetitive radioligand binding assays are used to determine the relative affinities (K i values) of test compounds for binding to a receptor site in a membrane homogenate or cells. They are performed by incubating a range of concentrations of the unlabeled test compound with a fixed concentration of radioligand and measuring the IC 50 (nM) of the … WebMar 30, 2024 · To do so, there are two general strategies: (1) performing measurements directly on cells or cell fragments; (2) extracting the receptor from its natural environment, …
