Antigen Background

Soy protein in a variety of forms is the basis of many low cholesterol foods and may also be incorporated in animal meat products.


renatured soy protein extracted from soy acetone powder with hot urea.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.


Anti-Soy Protein antibody produced in rabbit was used for soy quantification in natural rubber latex glove extracts by ELISA at 1:2000 dilution. It was used as a control in supershift analysis of growth-hormone-induced protein binding to lactogenic hormone-responsive region.

Biochem/physiol Actions

Soy protein is a rich source of isoflavones that act as estrogen analogs. They exert both estrogenic and anti-estrogenic effects depending on the tissue in which they act. Isoflavones effect the lipid and bone metabolism and may act as a potential alternative to estrogen in post-menopausal women.

General description

Some cross-reaction is observed with extracts from wheat flour and ovalbumin; no cross-reaction is observed with extracts from maize, rice, potato flour, casein, or meat.
