Identification of conjugated estrogen metabolites in dog plasma following administration of estriol-2,4,6,7-3H.
Following the constant infusion of 2,4,6,7-3H-estriol in male dogs for a period of 90 minutes, the radioactive metabolites present in arterial plasma were separated by solvent partition, DEAE-Sephadex, Celite partition and thin layer chromatography. The identities of the individual estrogens and estrogen conjugates were confirmed by specific activity determinations after chromatography in several different solvent systems, enzyme hydrolysis and chromatography of the unconjugated steroids and their derivatives.
