ABSTRACT:
This invention relates to the determination of in vivo exposure to dioxinlike compounds and the in vitro quantitation of dioxinlike compounds based on protein tyrosine phosphorylation as mediated by the Ah receptor. The extent of protein tyrosine phosphorylation is determined by monoclonal antibodies to protein tyrosine phosphate. The amount and nature of protein tyrosylphosphate is quantitatively related to the in vivo or in vitro concentration of dioxin to which animals or cells were exposed. This method permits detection of dioxinlike compounds at concentrations in the parts per trillion and parts per billion range.
