Figure 1. L-Epinephrine-induced concentration-dependent stimulation of intracellular calcium mobilization in CHO-K1/ADRB1/Gα15 cells. The cells were loaded with Calcium-4 prior to being stimulated with agonist L-Epinephrine (Cat. No. HY-B0447B; MCE). The intracellular calcium change was measured by FLIPR. The relative fluorescent units (RFU) were plotted against the log of the cumulative doses of L-Epinephrine (Mean ± SEM, n = 3). The EC50 of L-Epinephrine on this cell was 10.52 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. »
