title: Lack of oestradiol-DNA binding in mouse embryo cell cultures or following rat-liver microsomal metabolism.
abstract: Oestradiol-17beta was compared to benzo[a]pyrene (BP) for its ability to bind to the DNA of mouse embryo cells in culture or to DNA added to a rat liver microsomal incubation mixture. No significant binding was found in embryo cells (at least 100-fold less than for BP). Microsomal incubation resulted in apparent oestradiol binding to a reisolated DNA-containing complex, but most of this was lost when the DNA was freed of RNA and protein.
