| | SERT Radioligand Binding Assay |
| Description: | Compounds were dissolved in 100% DMSO at a concentration 100 times the desired highest assay concentration, serially diluted 1:3 in 100% DMSO, and 0.4 μl/well of each solution was dispensed to a Nunc polypropylene, round bottom, 384-well plate. 100% inhibition is defined with 0.4 μl/well of 1 mM fluoxetine dissolved in DMSO. 20 μl/well of a 2× membrane preparation (15 ug/ml in 50 mM Tris-Cl, pH 7.5, 120 mM NaCl, 5 mM KCl) and 20 μl/well of a 2× radioligand solution (520 pM [125I]RTI-55 in 50 mM Tris-Cl, pH 7.5, 120 mM NaCl, 5 mM KCl) were added to each well and the reaction incubated for 1 hour at room temperature. The contents of the assay plate were then transferred to a Millipore MultiscreenHTS GF/B filter plate which was pretreated with 0.5% PEI for at least one hour. The plate was vacuum filtered and washed with 7 washes of 100 μl/well 50 mM Tris-Cl, pH 7.5, 120 mM NaCl, 5 mM KCl chilled to 4° C. The filtration and washing were completed in less than 90 seconds. The plates were air-dried overnight, 12 μl/well of MicroScint scintillation fluid added, and the plates counted in a Trilux. |
