| | Affinity at Human D3 Receptors in Competitive Binding Assay Using [3H]spiperone |
| Description: | Aliquoted membrane preparations were incubated with 0.7 nM [3H]spiperone (PerkinElmer) in the presence or absence of test compound in 96-well plates for 120 minutes at 37° C. in an incubation buffer containing 50 mM Tris-HCl, 1.4 mM ascorbic acid, 0.001% bovine serum albumin, and 150 mM NaCl, at pH 7.4, with 1% DMSO in a final reaction volume of 222 μL. Non-specific binding (NSB) was determined in the presence of 25 μM(S)-(-)-sulpiride (Sigma Aldrich). After incubation, samples were filtered on GF/C filter plates (PerkinElmer), washed, and Microscint-20 scintillation cocktail was added. Radioactivity was determined in a MicroBeta2 microplate counter (PerkinElmer). |
