Abstract: Gel-permeation high performance liquid chromatography was used to examine the molecular characteristics of the cytosolic and nuclear receptors for 2,3,7,8-tetrachlorodibenzo-p-dioxin. The physical properties for this receptor previously established by sucrose-density gradient analysis have been maintained by the technique. The high performance liquid chromatography method offers the advantages of rapid separation and reproducibility thus minimizing possible effects of proteolytic enzymes or dissociation of the ligand-receptor complex. The specific binding of [3H]2,3,7,8-tetrachlorodibenzo-p-dioxin as measured by this system also corresponds quantitatively to that determined by the hydroxyapatite method. These methods will facilitate a further understanding of the biochemical actions of 2,3,7,8-tetrachlorodibenzo-p-dioxin and related compounds, as well as an understanding of the physiological function of this receptor molecule.
