Human ADRB3

Figure. Concentration-dependent activation of ADRB3 by isoproterenol

Reporter cells were transfected with either the expression plasmid for human adrenoceptor beta 3 (ADRB3) or the mock plasmid and treated with various concentrations of isoproterenol. 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 47 nM.
