| Description: | The binding assay was performed in melatonergic MT1 and MT2 receptors in order to check the receptor affinity for the ligand, i.e., the ability of the molecule to bind to the respective receptors. The Ki described in the results is the dissociation constant and measures the affinity of a non-radioactive test compound for the receptor. The IC50 shows the concentration of the substance required for achieving 50% inhibition of the receptors. Kd shows the affinity of the radio ligand to the receptor. Receptor inhibition is measured by the % of inhibition a binding specific control. Recombinant human cells (CHO-derived) and [1251]2-iodomelatonin compound labeling were used followed by incubation and detection at concentration of 0.01-0.05 nM by Scintillation Count, with Kd 0.04 nM and 0.085 nM, respectively. Incubation was performed for 60-120 min at 37° C. |
