Small intestinal mucosa of rats was tested for the presence of estrogen receptors. For determination of estrogen receptors  3H-estradiol 17-beta binding assay with or with our excess 1H-estradiol 17-beta was used. Three sub cellular fractions including nuclei, microsomes and cytosol, were analyzed. Some animals were pretreated with 1H-estradiol in order to determine whether it induces an increase in specific binding … Preberite več >>
