| Description: | Radioligand binding to human GlyT1c transporter-expressing membranes was carried out as described in Mezler et al., Molecular Pharmacology 74:1705-1715, 2008.More specifically, [3H]-(R)-NPTS radioligand binding to human GlyT1c transporter-expressing membranes was measured in duplicate in a total volume of 200 ul in 96-well plates. To 100 ul of membrane suspension (yielding a final membrane protein concentration of 50 ug/ml) in assay buffer (120 mM NaCl, 2 mM KCl, 10 mM Hepes, 1 mM MgCl2, 1 mM CaCl2, pH 7.5) 80 ul of [3H]-(R)-NPTS (0.5 nM final) were added in assay buffer. For competition experiments 10 ul of buffer or unlabeled compound solution obtained from dilution series of test compounds in DMSO followed. An intermediate 1:10 dilution in assay buffer yielded a final DMSO concentration of 1%. Non-specific binding was determined in the presence of 10 uM Org24598 (or its racemate Org24461) for [3H]-(R)-NPTS. |
