Figure 1. Somatostatin-14-induced concentration-dependent stimulation of intracellular calcium mobilization in CHO-K1/SST4/Gα15 cells. The cells were loaded with Calcium-4 prior to being stimulated with agonist somatostatin-14. The intracellular calcium change was measured by FLIPR. The relative fluorescent units (RFU) were normalized and plotted against the log of the cumulative doses of Somatostatin-14 (Mean ± SEM, n = 3). The EC₅₀ of Somatostatin-14 on this cell was 0.98 μM.

Notes:
EC₅₀ value is calculated with four parameter logistic equation:
Y=Bottom + (Top-Bottom) / (1+10^((LogEC₅₀-X)*Hill Slope))
X is the logarithm of concentration. Y is the response
Y is RFU and starts at Bottom and goes to Top with a sigmoid shape.

Figure 2. Dose dependent changing of intracellular cAMP upon treatment with Somatostain-14 in CHO-K1/SST4/Gα15 cells. d2 acceptor fluorophore-labeled cAMP and intracellular cAMP in CHO-K1/SST4/Gα15 cells competitively bind with Europium-labeled anti-cAMP monoclonal antibody. The FRET signal decreases as the intracellular cAMP concentration rises and was measured by PHERAstar FSX (BMG). The EC₅₀ of Somatostatin-14 on CHO-K1/SST4/Gα15 cells was 5.26 nM.
