A facile and sensitive chemiluminescence enzyme-linked immunosorbent assay (ELISA) of estriol 3-sulfate using a bridge-heterologous system was established. 6 alpha-Hydroxyestriol 3-sulfate 6-hemisuccinate was synthesized as a novel hapten. Antisera were raised in male guinea-pigs against 6 alpha-hydroxyestriol 3-sulfate 6-hemisuccinate-bovine serum

Different estrogen-3-sulfates (estrone-3-sulfate, estradiol-3-sulfate, and estriol-3-sulfate) can provoke important biologic responses in different mammary cancer cell lines; there is a significant increase in progesterone receptor. However, no significant effect was observed with estrogen-17-sulfates. The reason for the biologic response of

A highly specific anti-estriol 3-sulfate antiserum was treated with 50% ammonium sulfate, and the crude globulin fraction was coupled to CNBr-activated Sepharose-4B. Addition of 0.1M Tris-HC1 buffer (pH 8.3) containing 0.1M glutamine to the solution of antigen-antibody enabled assaying without

The R-27 cell line is a variant clone derived from the MCF-7 human breast cancer cell line which has lost its inhibitory response to anti-estrogens. In the present study, we have compared the biological responses to estriol (E3), estriol-3-sulfate (E3-3-S)

Antisera were raised in male guinea pigs against 6-oxoestriol 3-sulfate O-carboxymethyloxime-bovine serum albumin (BSA) conjugate. The antisera to this antigen exhibited high affinity (Ka=4.7 X 10(9)M-1) and excellent specificity for estriol 3-sulfate, showing slight cross-reactions (less than 0.43%) with other
