Scintillation Proximity Assay (SPA): Briefly, serial dilutions of the test compounds were placed in a 96-well plate to which were added SPA beads, membrane and radioligand. The assay conditions for each opioid receptor subtype are described in Table 10 below. The plates were incubated for 8 hours-overnight at room temperature, spun at 1000 rpm to pellet the SPA beads, and radioactivity was measured using the TopCount microplate Scintillation counter. Specific binding at each concentration of test compound was calculated by subtracting the non-specific binding measured in the presence of excess cold ligand. IC50 values were obtained by non-linear regression of specific binding versus concentration curves and Ki values were calculated using Kd values that were experimentally pre-determined for each lot of membrane preparations. Homo sapiens 133.48 nM
HiRange Homogenous Time-Resolved Fluorescence (HTRF) Assay: Briefly, suspensions of cells expressing either the mu, kappa or delta opioid receptors were prepared in buffer containing 0.5 mM isobutyl-methyl xanthine (IBMX). Cells were incubated with varying concentrations of PEG-opioid conjugates and 3 uM forskolin for 30 minutes at room temperature. cAMP was detected following a two-step assay protocol per the manufacturer's instructions and time resolved fluorescence was measured with the following settings: 330 nm excitation; 620 nm and 665 nm emission; 380 nm dichroic mirror. The 665 nm/620 nm ratio is expressed as Delta F % and test compound-related data is expressed as a percentage of average maximum response in wells without forskolin. EC50 values were calculated for each compound from a sigmoidal dose-response plot of concentrations versus maximum response. Homo sapiens 478.0 nM
