摘要: Binding of [2,4,6,7-3H]-estradiol or its metabolites in the liver tissue unprimed roosters and those given repeated doses estradiol has been studied. Electron autoradiographs show localization radioactivity on endoplasmic reticulum, mitochondria, nuclear membrane nucleolar extranucleolar chromatin hepatocytes. Repeated hormone to bird increase number binding sites. However, dissociation constant (Kd) for heavy pellet fraction extractable with 0·4 M KC1 remains essentially unchanged.
