Description
Estrone sulfate, a biologically inactive form of estrogen, is a major circulating plasma estrogen that is converted into the biologically active estrogen, estrone (E1) by steroid sulfatase (STS). strone sulfate can be used for the research of breast cancer.

How to use
In Vitro:
T47D cells are stably transfected with SOAT and incubated under increasing concentrations of Estrone sulfate and estradiol at physiologically relevant concentrations. Cell proliferation is significantly increased by 1 nM estradiol as well as by Estrone sulfate with EC50 of 2.2 nM.
