Figure 1. PAF-induced concentration-dependent stimulation of intracellular calcium mobilization in CHO-K1/PTAFR cells. The cells were loaded with Calcium-4 prior to being stimulated with agonist PAF. 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 PAF (Mean ± SD, n = 2). The EC₅₀ of PAF on the cells was 0.13 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 RFU and starts at Bottom and goes to Top with a sigmoid shape.

CHO-K1/PTAFR Stable Cell Line

Recombinant CHO-K1 cells stably overexpress human platelet activating factor receptor (PTAFR) on the surface and contain high levels of G protein Gαq and Gαi to couple with the receptor in downstream signaling pathways.
