Figure 1: Kisspeptin-10-induced concentration-dependent stimulation of intracellular calcium mobilization in CHO-K1/KiSS1 cells. The cells were loaded with Calcium-4 prior to being stimulated with KiSS1 receptor agonist, Kisspeptin-10. The intracellular calcium change was measured by FLIPRTETRA. The relative fluorescent units (RFU) were normalized and plotted against the log of the cumulative doses (5-fold dilution) of LPA (Mean ± SD, n = 2). The EC50 of LPA on CHO-K1/KiSS1 cells was 14.2 nM.
Note:
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 and starts at Bottom and goes to Top with a sigmoid shape.
