Description
Figure. Concentration-dependent activation of GHRHR by GHRH. Reporter cells were transfected with the expression plasmid for growth hormone releasing hormone receptor (GHRHR) and treated with various concentrations of growth hormone–releasing hormone (GHRH). 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 2.0 nM.
