Complete Growth Medium | Complete Growth Medium: DMEM, 10% FBS. |
Freeze Medium-DATA | 50% DMEM (Cat. No. 10566, Life Technologies), 45% FBS (Cat. No. 10099-141, Gibco), 5% DMSO (Cat. No. D2650, Sigma). |
Figure 1. PTH (1-34)-induced luciferase expression in HEK293/PTH2/CRE-Luc cells. After stimulation by agonist PTH (1-34), the cells are determined with Fire-Lumi™ Luciferase Assay System (Cat. No. L00877C-100, Genscript) and the relative luminescence units (RLU) were recorded by plate reader (Pherastar, BMG). The RLU were plotted against the log of the cumulative doses of PTH (1-34) (Mean ± SEM, n = 3). The EC50 of PTH (1-34) on cells was 0.68 nM.

Figure 2. Dose dependent stimulation of intracellular cAMP accumulation upon treatment with PTH (1-34) in HEK293/PTH2/CRE-Luc cells. d2 acceptor fluorophore-labeled cAMP (Cat. No. 62AM4PEC; Revvity) and intracellular cAMP in HEK293/PTH2/CRE-Luc cells competitively bind with Europium Cryptate-labeled anti-cAMP monoclonal antibody. The FRET signal decreases as the intracellular cAMP concentration rises and was measured by plate reader (Pherastar, BMG). The EC50 of PTH (1-34) on cells was 23.07 nM. »
