Human HTR1F

Figure. Concentration-dependent activation of HTR1F by serotonin

Reporter cells were transfected with either the expression plasmid for human 5-hydroxytryptamine receptor 1F (HTR1F) 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 3.3 nM.
