Binding
Radioligand Dose-Displacement Binding Assay: Radioligand dose-displacement binding assays for t-opioid receptors used 0.3 nM [3H]-diprenorphine (Perkin Elmer, Shelton, Conn.), with 5 mg membrane protein/well in a final volume of 500 ul binding buffer (10 mM MgCl2, 1 mM EDTA, 5% DMSO, 50 mM HEPES, pH 7.4). Reactions were carried out in the absence or presence of increasing concentrations of unlabeled naloxone. All reactions were conducted in 96-deep well polypropylene plates for 2 hr at room temperature. Binding reactions were terminated by rapid filtration onto 96-well Unifilter GF/C filter plates (Perkin Elmer, Shelton, Conn.), presoaked in 0.5% polyethylenimine using a 96-well tissue harvester (Perkin Elmer, Shelton, Conn.) followed by performing three filtration washes with 500 ul of ice-cold binding buffer. Filter plates were subsequently dried at 50° C. for 2-3 hours. BetaScint scintillation cocktail (Perkin Elmer, Shelton, Conn.) was added (50 ul/well), and plates were counted using a Packard Top-Count.
