Assay Method Information

Assay Name:  Binding Assay
Description:  Cell membrane homogenates (25 μg protein) were incubated for 120 min at 37° C. with 0.5 nM [3H]CP 55940 (the reference standard [Rinaldi-Carmona, 1996 #1320]) in the absence or presence of the test compound in a buffer containing 50 mM Tris HCl (pH 7.4), 5 mM MgCl2, 2.5 mM EDTA, and 0.3% bovine serum albumin (BSA). Nonspecific binding was determined in the presence of 10 μM WIN 55212-2. After being incubated, the samples were filtered rapidly under vacuum through glass fiber filters (GF/B; Packard) presoaked with 0.3% PEI and rinsed several times with ice-cold buffer containing 50 mM Tris HCl (pH 7.4) and 0.5% BSA using a 96-sample cell harvester (Unifilter; Packard). The filters were dried then counted for radioactivity in a scintillation counter (Topcount; Packard) using a scintillation cocktail (Microscint 0; Packard).
