In this type of assay, a single concentration of radioligand (usually an agonist) is used in every assay tube. The ligand is used at a low concentration, usually at or below its Kd value. The level of specific binding of the radioligand is then determined in the presence of a range of concentrations of other competing non-radioactive compounds (usually antagonists), in order to measure the potency with which they compete for the binding of the radioligand. Competition curves may als… WebApr 12, 2024 · The interaction between ligands and receptors is often described in terms of 50% inhibitory concentrations ( IC50 ). However, IC50 values do not accurately reflect the dissociation constants ( Kd ), and the domain of application and precision of proposed approximations for Kd estimation are unclear.
