CHO-K1/GALR1/Gα15 Stable Cell Line

Figure 1. Galanin (1-30)-induced concentration-dependent stimulation of intracellular calcium mobilization in CHO-K1/GALR1/Gα15 cells. The cells were loaded with Calcium-4 (Cat. No. R8142; Molecular Devices) prior to stimulation with GALR1 agonist, galanin (1-30). The intracellular calcium change was measured by FLIPRTETRA. The relative fluorescent units (RFU) were recorded and normalized to plot against the log of the cumulative doses of galanin (1-30) (mean ± SEM, n = 3). The EC50 of galanin (1-30) on CHO-K1/GALR1/Gα15 cells was 51.81 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 % stimulation of ∆RFU and starts at Bottom and goes to Top along a sigmoid curve.

CHO-K1/GALR1/Gα15 Stable Cell Line
