| Description: | Activation of GLP-1 receptor is known to stimulate cyclic AMP (cAMP) production in cells which indicates primary coupling to the Gαs subunit of the G protein heterotrimeric complex. Evidence suggests signaling through Gαs induced CAMP stimulation elicits the desired pharmacological response regarding insulin release from pancreatic β-cells. To optimize functional activity directed toward Gαs coupling, a HEK293/CRELuc cell line developed by HDB stably expressing the GLP-1 Receptor was used. 200× concentration of compound working solutions were prepared (Agilent Technologies Bravo) with 1/2 log serial dilution in 384-well Echo LDV plate (Labcyte, Cat #LP-0200). 50 nL/well 200× concentration of compound working solutions were moved to 384-well white low volume plate (Greiner, Cat #784075) using Labcyte ECHO550. 1×105 cells/mL HEK293/GLP1R/CRE-LUC (HD Biosciences) cell suspensions prepared with assay buffer [DPBS containing 0.5 mM IBMX (Sigma,Cat #I5879) and 0.1% BSA (GENVIEW, Cat #FA016-100 g)], 10 uL cell suspensions were added to each well of previous generated assay plate which already contains 50 nl compound at 200× concentration using ThermoFisher Multidrop Combi (1000cells/well). Seal the plate and incubate at 37° C. with 5% CO2 for 30 min. |
