dissociation constants and binding capacities were determined for either receptor in the absence of the other [ e.g. , estrone receptor ( e1r ) in the cytosol or nuclear residue from 17 beta-estradiol-stimulated cells ] or , when both receptors were present , a saturating amount of the other estrogen ( unlabeled ) was added to the assay mixture ( e.g. , the salt-extractable nuclear receptors ) .
