| Description: | The efficacy of GLP-1 receptor agonists was studied in a cAMP functional assay using HEK-293 Cells expressing the cloned human GLP-1 receptor. GLP-1-expressing cells (10,000-20,000 cells per 0.1 mL) were plated in 96-well plates in Dulbecco's modified eagles media (DMEM) containing 10% fetal bovine serum, 2 mg/mL G418 and penicillin-streptomycin. Following overnight incubation of cells, media was removed, and compounds (at concentrations ranging from 0.0001 to 100 μM) were added to monolayer cells in Iscove's modified dulbecco's medium (IMDM), 100 μM RO 20-1724 PDE inhibitor, 0.1% BSA, 2% DMSO in a final volume of 100 μL, and incubated for 30 min at 37° C. 95%02, 5% CO2 in a humidified incubator. Alternatively, cells were harvested and combined with compounds in suspension using the buffer and protocol described above. cAMP was quantified using a homogenous time-resolved fluorescence detection system (cAMP dynamic, CIS bio International). |
