Figure 1. Calcitonin-induced concentration-dependent stimulation of intracellular calcium mobilization in CHO-K1/Gα15/AMY1 cells. The cells were loaded with Calcium-4 (Cat. No. R8142; Molecular Devices) prior to stimulation with AMY1 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/Gα15/AMY1 cells was 0.11 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 along a sigmoid curve.

Figure 2. Dose dependent stimulation of intracellular cAMP accumulation upon treatment with amylin in CHO-K1/Gα15/AMY1 cells. d2 acceptor fluorophore-labeled cAMP (Cat. No. 62AM4PEC; Revvity) and intracellular cAMP in CHO-K1/Gα15/AMY1 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 amylin on CHO-K1/Gα15/AMY1 cells was 4.94 nM.

CHO-K1/Gα15/AMY1 Stable Cell Line

Recombinant CHO-K1 cells stably overexpress human receptor activity modifying protein 1 (RAMP1) and calcitonin receptor (CTR) on the surface. Amylin receptors (AMYR) are a class of special protein heterodimers, composed of a CTR combined with one of three homologous receptor activity-modifying proteins (RAMP1, RAMP2, RAMP3), forming three subtypes (AMY1, AMY2, AMY3). This cell contain high levels of G protein Gαs to couple with the receptor in downstream signaling pathways.
