The objective of the research was to determine whether the levels of binding between oestrogenic chemicals and pure oestrogen receptor could be quantified in vitro using ligand receptor interaction analysis. The hope was that such technology might be usefully applied to quantifying human exposure to oestrogens in epidemiological investigations. The first approach attempting to reproduce published reports on the interaction of the ligand/receptor complex with an oestrogen response element were unsuccessful. In a second approach interactions between ligand and oestrogen receptors were detected using a BSA-oestradiol and BSA-zearalenone conjugate as a competitor – although methodological problems still exist.
