| [3H]-NMS Binding Assay |
Description: | Assays were carried out at 25° C. Membrane preparations from stably transfected chinese hamster ovary-K1 cells (CHO) expressing the genes for the human muscarinic receptors Hm3 were used. For determination of IC, membrane preparations were suspended in DPBS to a final concentration of 89 μg/ml for the Hm3 subtype. The membrane suspension was incubated with the tritiated compound for 60 min. After incubation the membrane fraction was separated by filtration and the bound radioactivity determined. Non specific binding was determined by addition of 10^−4 M atropine. At least six concentrations were assayed in duplicate to generate individual displacement curves. |
