Figure. Concentration-dependent activation of SSTR3 by somato­statin-14. Reporter cells were transfected with either the expression plasmid for somato­statin receptor 3 (SSTR3) or the mock plasmid and treated with various concentrations of somato­statin-14. 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 3.2 nM.
