Human ADRA1D

Figure. Concentration-dependent activation of ADRA1D by L‐phenylephrine

Reporter cells were transfected with either the expression plasmid for human adrenoceptor alpha 1D (ADRA1D) or the mock plasmid and treated with various concentrations of L‐phenylephrine. Data points shown are the mean ± SEM of an experiment (n = 3), and the curve is a fit to Hill equation with an EC50 of 67 nM.
