Radioactivity in the Uteri of Rats Following Injection of Estrone-16-C14

Abstract

The partitioning of radioactivity in uterine luminal fluid and uteri from rats injected with estrone-16-C¹⁴ is described. Though a minute amount of radioactivity is present in the phenolic fraction, the major portion is present as a water soluble component. No steroidal radioactivity was present as either a conjugated or protein-bound form.
