Figure UK14304-induced concentration-dependent stimulation of intracellular calcium mobilization in CHO-K1/ADRA2B/Gqi5 cells. The cells were loaded with Calcium-4 prior to being stimulated with agonist UK14304. The intracellular calcium change was measured by FLIPR. The relative fluorescent units (RFU) were normalized and plotted against the log of the cumulative doses (5-fold dilution) of UK14304 (Mean ± SD, n = 2). The EC50 of UK14304 on this cell was 0.12 µM.
Notes:
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
