2542691-5	1989	Sucrose density gradient centrifugation revealed that both 2- and 4-hydroxyestradiol inhibited the binding of estradiol-17 beta to both the 4S and 8S isoforms of the estrogen receptor in a competitive manner, with a Ki = 0.94 nM for 2-hydroxyestradiol and a Ki = 0.48 nM for 4-hydroxyestradiol.
