Human ADRA2B

Figure. Concentration-dependent activation of ADRA2B by noradrenaline

Reporter cells were transfected with either the expression plasmid for human adrenoceptor alpha 2B (ADRA2B) or the mock plasmid and treated with various concentrations of noradrenaline. 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 33 nM.
