HTR5A

Figure. Concentration-dependent activation of HTR5A by serotonin
Reporter cells were transfected with either the expression plasmid for 5-hydroxytryptamine receptor 5A (HTR5A) or the mock plasmid and treated with various concentrations of serotonin. 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 85 nM.
