Binding and effects of catecholestrogens on adenylate cyclase activity, and adrenoceptors, benzodiazepine and GABA receptors in guinea-pig hypothalamic membranes

Catecholestrogen (CE) binding to guinea-pig hypothalamic membranes was assessed by using [3H]2-hydroxyestrone (2-OHE2) as a ligand. Binding was maximal at pH 7.4 and 37°C, and after 10 min incubations. A high affinity binding site with dissociation constant (KD) = 0.20 ± 0.02 nM and site concentrati...
