Description
Figure. Concentration-dependent activation of VIPR2 by VIP. Reporter cells were transfected with either the expression plasmid for vasoactive intestinal peptide receptor 2 (VIPR2) or the mock plasmid and treated with various concentrations of vasoactive intestinal peptide (VIP). 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 13 nM.
