Unspecific Binding Capacity of Androgen Receptors in the Rat Uterus

Abstract

Rat uterine cytosol receptor homogenate binds estradiol and testosterone alike. Saturation and displacement studies were done with these two hormones. Testosterone displaced only testosterone while estradiol displaced estradiol as well as testosterone. The experiments call attention to the unspecific binding capacity of rat uterine androgen receptors.
