Estrone sulfate sodium (Standard) is the analytical standard of Estrone sulfate sodium (HY-113293B). This product is intended for research and analytical applications. Estrone sulfate sodium is an inactive endogenous estrogen that can be converted into Estrone (HY-B0234) and Estradiol (HY-B0141). Estrone sulfate sodium is also a substrate of the OATP1B3 transporter. Estrone sulfate sodium can be converted into Estrone and Estradiol in normal mammary parenchymal cells. Estrone sulfate sodium stimulates the growth of nitrosomethylurea-induced mammary tumors in ovariectomized rats and the colony formation of dispersed nitrosomethylurea mammary cells, with conversion into Estrone and Estradiol occurring both in vivo and in vitro during this process. Estrone sulfate sodium is applicable to breast cancer-related research.
