title: Preparation of specific antisera to estrone-3-glucuronide and estriol-3-glucuronide.
abstract: The preparation and antigenic properties of estrone-3-glucuronide- and estriol-3-glucuronide-bovine serum albumin conjugates in which the hapten is linked to the carrier protein through an (O-carboxymethyl)oxime bridge at the C-6 position on the steroid nucleus, have been described. Antibodies raised against the two immunogens in the rabbit possessed high specificity to estrone-3-glucuronide and estriol-3-glucuronide, respectively, exhibiting little cross-reactivities with other estrogen conjugates and no cross-reactions with related steroids except for free estrogens, their 3-methyl ethers and 3-sulfates. The cross-reactive antibodies were eliminated by partial immunoadsorption on affinity chromatographic media using the estrone-3-methyl ether 17-(O-carboxymethyl)oxime- and estriol-3-methyl ether 16 (or 17)-hemisuccinate-aminohexyl Sepharose conjugates, respectively. The purified antisera exhibited no cross-reactivities with free estrogens and ring A conjugates of estrone and estriol.
