Description
Figure. Concentration-dependent activation of DRD1 by dopamine. Reporter cells were transfected with either the expression plasmid for dopamine receptor D1 (DRD1) or the mock plasmid and treated with various concentrations of dopamine. 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 260 nM.
