Description
Figure. Concentration-dependent activation of PTGIR by beraprost. Reporter cells were transfected with either the expression plasmid for prostaglandin I2 receptor (PTGIR) or the mock plasmid and treated with various concentrations of beraprost. 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 130 nM.
