| Description: | The affinity of compounds to D1 and D2 dopamine receptors were determined by competition binding assays. Membrane homogenates of HEK293T cells were stably transfected with D1, or D2 receptors. Duplicated tubes were incubated at 30° C. for 50 mins (for D1, and D2) with increasing concentrations of respective compound and with [3H]SCH23390 (for D1 dopamine receptors), or [3H]Spiperone (for dopamine D2 receptor) in a final volume of 200 μL binding buffer containing 50 mM Tris, 4 mM MgCl2, pH 7.4. Nonspecific binding was determined by parallel incubations with either 10 μM SCH23390 for D1, or Spiperone for D2 receptors respectively. The reaction was started by addition of membranes (15 ng/tube) and stopped by rapid filtration through Whatman GF/B glassfiber filter and subsequently washed with cold buffer (50 mM Tris, 5 mM EDTA, pH 7.4) using a Brandel 24-well cell harvester. Scintillation cocktail was added and the radioactivity was determined in a MicroBeta liquid scintillation counter. |
