Inhibition of estradiol sulfonation in sheep placental samples, measured at 1 nM estradiol, by various concentrations of 4′OH-CB79. The lines shown are the fits of fraction control activity versus log [4′OH-CB79] to sigmoidal dose–response curves for each of 3 individuals. Error bars on each line indicate the S.D. of assay replicates at each concentration of 4′OH-CB79. The mean IC50 value is indicated on the graph.
