| | Radioligand Binding Assay |
| Description: | Human GPR43 radioligand binding assay is performed by adding successively in the wells of a 96 well plate (Master Block, Greiner, 786201), 50 ul of compound of the invention at increasing concentrations (diluted in assay buffer: 50 mM Tris pH 7.4), 25 ul radiolabeled antagonist (ie. compound no 277 described in EP10305100.9) diluted in assay buffer and 25 ul cell membrane extracts (10 ug protein/well). The final concentration of radiolabeled antagonist in the assay is 10 nM. The plate is incubated 60 min at 25° C. in a water bath and then filtered over GF/B filters (Perkin Elmer, 6005177, presoaked in 0.05% Brij for 2h at room temperature) with a Filtration unit (Perkin Elmer). The filters are washed 3 times with 0.5 ml of ice-cold wash buffer (50 mM Tris pH 7.4). 50 ul of Microscint 20 (Packard), is added and the plate is incubated 15 min on an orbital shaker and then counted with a TopCount for 1 min/well. |
