Background

11-keto Testosterone 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. 11-keto Testosterone binds the stickleback kidney androgen receptor (EC50 = 43 nM). 11-keto Testosterone, at 10 nM, significantly activates the human androgen receptor expressed in zebrafish liver cells. This product is intended for research and forensic applications. Glpbio products containing Certified Reference Material in the name are highly qualified materials manufactured and tested to meet ISO/IEC 17025 and ISO Guide 34 international guidelines for reference materials. These materials are tested using validated analytical methods on qualified instrumentation to ensure traceability to SI units of measure. Glpbio’s CRMs are tested for Homogeneity and Stability and are provided with a certificate stating the CRM property value(s) along with the combined uncertainty of the property value(s). These materials are intended for quantitative applications where quantitative accuracy and uncertainty are critical. Glpbio is committed to providing quality products to its customers as evidenced by its accreditation to the ISO/IEC 17025 and ISO Guide 34 standards. All traceable CRMs may be distinguished by their CofAs and can be downloaded below using the batch number located on the product label.

Calculation results:

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
3. All of the above co-solvents are available for purchase on the GlpBio website.
