| Description: | HEK293 cells expressing human GPR10 were maintained in Dulbecco's Modified Eagles' medium supplemented with 10% fetal bovine serum, 1% penicillin-streptomycin and 20 mM HEPES at 37° C. in a 5% CO2 incubator. GPR10-expressing HEK293 cells were placed in poly-D-lysine coated 96-well culture plates and cultured for 18-24 hr before the test at a density of 3×104 cells/well. The cells were incubated with 2.5 nM Fluo-8 for 1 hr at room temperature in Recording Buffer containing 1% bovine serum albumin, 0.01% pluronic F-127 and 20 mM HEPES, Hanks Balanced Buffered Saline, pH 7.4. The cells were incubated with test compounds for 15 min at room temperature, and then PrRP (the final concentration, 1 nM) was added into the medium. The changes in intracellular calcium-dependent fluorescence were monitored using a fluorescence imaging plate reader (FDSS3000, Hamamatsu Photonics K.K.). Fluo-8 fluorescence was measured with excitation at 490 nm and emission at 520 nm. |
