| Description: | 5-HT transporter binding assay for evaluating binding of the compound to the serotonin transporter was carried out using human recombinant serotonin transporter membrane (PerkinElmer Life and Analytical Sciences, USA) expressed in HEK293 cells and radioisotope [3H]Imipramine (PerkinElmer).That is, the test drug, 2 nM [3H]Imipramine, serotonin transporter membrane (9 ug/well), 120 mM NaCl and 50 mM Tris-HCl buffer (pH 7.4) containing 5 mM KCl were added to obtain a reaction mixture with a final volume of 0.25 ml. After incubation for 30 minutes at 27° C., the mixture was quickly passed through a Filtermat A glass fiber filter (PerkinElmer) pre-soaked with 0.5% (w/v) PEI (polyethyleneimine) using Inotech Harvester (Inotech) to terminate the reaction. After washing with cold washing buffer (50 mM Tris-HCl, pH 7.4, 154 mM NaCl) solution, the filter was covered with MeltiLex and sealed in a sample bag. After drying in an oven, radioactivity was counted using MicroBeta Plus (Wallac). |
