Description
Figure. Concentration-dependent activation of GRPR by GRP. Reporter cells were transfected with either the expression plasmid for gastrin releasing peptide receptor (GRPR) or the mock plasmid and treated with various concentrations of gastrin-releasing peptide (GRP). 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 1.3 nM.
