Agonistic Activity Assay: 293E cells (EBNA1-expressing IIEK293 cells, ATCC No. CRL-10852) were cultured in DMEM (1.0 g/ml Glucose-containing Dulbecco's modified Eagle medium, Nacalai Tesque) containing 10% bovine fetal serum in the presence of 250 ug/ml of G418. The cells were seeded on a 10 cm-diameter petri dish at 1.8ÿ106 cells/15 ml, and left to stand in a CO2 incubator (5% CO2, 37° C.) for 24 hours. Thereafter, human CaSR expression plasmid hCaSR/pcDNA3.1 was transfected with transfection reagent Mirus Trans IT 293 (Takara Bio). Following static culture in a CO2 incubator for 24 hours, the cells were harvested with 10% bovine fetal serum-containing DMEM and seeded on a poly-D-lysine coat 384 well plate (Falcon) at 15,000 cells/well. Following static culture in a CO2 incubator for 24 hours, the medium was removed and the resultant was added with 50 ul/well of Ca2+ fluorescent indicator Calcium 4 Assay Kit (Molecular Devices) dissolved in an assay buffer (146 mM NaCl, 5 mM KCl, 1 mM MgSO4, 1 mg/ml Glucose, 20 mM HEPES (PH 7.2), 1.5 mM CaCl2), and left to stand at 37° C. for an hour and then at room temperature for 30 minutes to allow intake of the indicator. The above-mentioned 384-well plate was transferred to FLIPR (Molecular Devices) and added with 12.5 ul/well of a compound dissolved in a 0.1% BSA-containing assay buffer to measure 3-minute change in the fluorescence intensity.Agonistic Activity Assay: 293E cells (EBNA1-expressing IIEK293 cells, ATCC No. CRL-10852) were cultured in DMEM (1.0 g/ml Glucose-containing Dulbecco's modified Eagle medium, Nacalai Tesque) containing 10% bovine fetal serum in the presence of 250 ug/ml of G418.

Agonistic Activity Assay: 293E cells (EBNA1-expressing IIEK293 cells, ATCC No. CRL-10852) were cultured in DMEM (1.0 g/ml Glucose-containing Dulbecco's modified Eagle medium, Nacalai Tesque) containing 10% bovine fetal serum in the presence of 250 ug/ml of G418. The cells were seeded on a 10 cm-diameter petri dish at 1.8ÿ106 cells/15 ml, and left to stand in a CO2 incubator (5% CO2, 37° C.) for 24 hours. Thereafter, human CaSR expression plasmid hCaSR/pcDNA3.1 was transfected with transfection reagent Mirus Trans IT 293 (Takara Bio). Following static culture in a CO2 incubator for 24 hours, the cells were harvested with 10% bovine fetal serum-containing DMEM and seeded on a poly-D-lysine coat 384 well plate (Falcon) at 15,000 cells/well. Following static culture in a CO2 incubator for 24 hours, the medium was removed and the resultant was added with 50 ul/well of Ca2+ fluorescent indicator Calcium 4 Assay Kit (Molecular Devices) dissolved in an assay buffer (146 mM NaCl, 5 mM KCl, 1 mM MgSO4, 1 mg/ml Glucose, 20 mM HEPES (PH 7.2), 1.5 mM CaCl2), and left to stand at 37° C. for an hour and then at room temperature for 30 minutes to allow intake of the indicator. The above-mentioned 384-well plate was transferred to FLIPR (Molecular Devices) and added with 12.5 ul/well of a compound dissolved in a 0.1% BSA-containing assay buffer to measure 3-minute change in the fluorescence intensity.Agonistic Activity Assay: 293E cells (EBNA1-expressing IIEK293 cells, ATCC No. CRL-10852) were cultured in DMEM (1.0 g/ml Glucose-containing Dulbecco's modified Eagle medium, Nacalai Tesque) containing 10% bovine fetal serum in the presence of 250 ug/ml of G418.
