CHO-K1/CCKA/Gα15 Stable Cell Line

Figure 1. CCK-8-induced concentration-dependent stimulation of intracellular calcium mobilization in CHO-K1/CCKA/Gα15 cells. The cells were loaded with Calcium-4 (Cat. No. R8142, Molecular Devices) prior to being stimulated with agonist CCK-8. The intracellular calcium change was measured by FLIPR. The relative fluorescent units (RFU) were recorded and plotted against the log of the cumulative doses of CCK-8 (Mean ± SEM, n = 3). The EC50 of CCK-8 on this cell was 0.45 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 with a sigmoid shape.

CHO-K1/CCKA/Gα15 Stable Cell Line

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