Description
Figure. Concentration-dependent activation of S1PR2 by S1P. Reporter cells were transfected with either the expression plasmid for sphingosine-1-phosphate receptor 2 (S1PR2) or the mock plasmid and treated with various concentrations of sphingosine 1-phosphate (S1P). Data points shown are the mean ± SEM of an experiment performed in triplicate, and the curve is a fit to Hill equation with an EC50 of 110 nM.
