Figure 1. NECA-induced concentration-dependent stimulation of intracellular calcium mobilization in HEK293/ADORA1/Gα15 cells. The cells were loaded with Calcium-4 (Cat. No. R8142; Molecular Devices) prior to stimulation with ADORA1 agonist, NECA (Cat. No. HY-103173, MCE). The intracellular calcium change was measured by FLIPRTETRA. The relative fluorescent units (RFU) were recorded and plotted against the log of the cumulative doses of NECA (mean ± SEM, n = 3). The EC50 of NECA on HEK293/ADORA1/Gα15 cells was 4.09 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 along a sigmoid curve. »
