Figure 1: Calcitonin-induced concentration-dependent stimulation of intracellular calcium mobilization in CHO-K1/CT/Gα15 cells. The cells were loaded with Calcium-4 (Cat. No. R8142; Molecular Devices) prior to stimulation with CT agonist, calcitonin. The intracellular calcium change was measured by FLIPR^TETRA. The relative fluorescent units (RFU) were recorded and normalized to plot against the log of the cumulative doses of calcitonin (mean ± SEM, n = 3). The EC₅₀ of calcitonin on CHO-K1/CT/Gα15 cells was 18.88 nM.

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 along a sigmoid curve.

Figure 2. Dose dependent stimulation of intracellular cAMP mobilization upon treatment with calcitonin in CHO-K1/CT/Gα15 cells. d2 acceptor fluorophore-labeled cAMP (Cat. No. 62AM4PEC; Revvity) and intracellular cAMP in CHO-K1/CT/Gα15 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 (Varioskan, Thermo Fisher). The EC₅₀ of calcitonin was 0.27 nM.

CHO-K1/CT/Gα15 Stable Cell Line

Recombinant CHO-K1 cells stably overexpress human calcitonin receptor (CT) on the surface and contain high levels of G protein Gαq and Gαs to couple with the receptor in downstream signaling pathways.
