    Product Description

    11-keto Testosterone (CRM) (Item No. 9002654) is a certified reference material that is structurally categorized as an androgen. It is a significant hormone in certain fish, regulating the development of sexual development and behavior.1,2 11-keto Testosterone binds the stickleback kidney androgen receptor (EC50 = 43 nM).3 11-keto Testosterone, at 10 nM, significantly activates the human androgen receptor expressed in zebrafish liver cells.3 This product is intended for research and forensic applications.

    WARNING This product is not for human or veterinary use.
