Figure 1. NECA-induced concentration-dependent stimulation of intracellular calcium mobilization in CHO-K1/ADORA3/Gα15 cells. The cells were loaded with Calcium-4 prior to being stimulated with an ADORA3 receptor agonist, NECA. The intracellular calcium change was measured by FLIPR. The relative fluorescence unit (RFU) were normalized and plotted against the log of the cumulative doses of NECA (Mean ± SEM, n = 3). The EC50 of NECA on this cell was 4.76 nM.
1. EC50 value is calculated with four parameter logistic equation:
Y=Bottom + (Top-Bottom)/(1+10^((LogEC50-X)*HillSlope))
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.
2. Signal to background Ratio (S/B) = Top/Bottom
