Human SSTR1

Figure. Concentration-dependent activation of SSTR1 by somatostatin‐14

Reporter cells were transfected with either the expression plasmid for human somatostatin receptor 1 (SSTR1) or the mock plasmid and treated with various concentrations of somatostatin‐14. 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 23 nM.
