Human SCTR

Figure. Concentration-dependent activation of SCTR by secretin

Reporter cells were transfected with either the expression plasmid for human secretin receptor (SCTR) or the mock plasmid and treated with various concentrations of secretin. Data points shown are the mean ± SEM of an experiment (n = 3), and the curve is a fit to Hill equation with an EC50 of 7.6 nM.
