Binding
Radioligand Dose-Displacement Binding Assay: Radioligand dose displacement assays used 0.4 nM [3H]-U69,593 (GE Healthcare, Piscataway, N.J.; 40 Ci/mmole) with 15 μg membrane protein (recombinant κ opioid receptor expressed in HEK 293 cells; in-house prep) in a final volume of 200 μl binding buffer (5% DMSO, 50 mM Trizma base, pH 7.4). Non-specific binding was determined in the presence of 10 μM unlabeled naloxone or U69,593. All reactions were performed in 96-well polypropylene plates for 1 hr at a temperature of about 25° C. Binding reactions were terminated by rapid filtration onto 96-well Unifilter GF/C filter plates (Perkin Elmer, Shelton, Conn.) presoaked in 0.5% polyethylenimine (Sigma). Harvesting was performed using a 96-well tissue harvester (Perkin Elmer, Shelton, Conn.) followed by five filtration washes with 2001 ice-cold binding buffer. Filter plates were subsequently dried at 50° C. for 1-2 hours.
