| | Measurement of Activity of GPR120 Agonist (Cell-Based Assay) |
| Description: | CHO-K1 cells expressing Ga16 and hGPR120 were dispensed into each well of a 96-well plate (3×104 cells/100 μl/well) and then incubated in 5% CO2, 37° C. incubator for 18 hours. Each well was treated with 100 μl of Calcium 5 dye (Molecular Devices) solution including 2% DMSO and then incubated in 5% CO2, 37° C. incubator for 1 hour. Serially diluted GPR120 agonists were prepared to a final concentration of 0.5% DMSO in a 96-well plate. Each well was treated with 50 μl of the agonist compounds using Plexstation II, and then fluorescence was measured at Ex 485 nm and Em 525 nm.Fluorescence increased by the serially diluted GPR120 agonists is calculated as a relative percent (%) value based on the fluorescence represented by the treatment of 1% DMSO only. EC50 refers to the concentration of agonist which shows 50% of maximum fluorescence increased by the treatment of agonist. The calculation of measurement was carried out by using statistical software (Prizm). |
