Description
Figure. Concentration-dependent activation of GIPR by GIP. Reporter cells were transfected with the expression plasmid for gastric inhibitory polypeptide receptor (GIPR) and treated with various concentrations of gastric inhibitory polypeptide (GIP). 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 3.4 nM.
