Steroid hormones are essential in numerous physiological processes including metabolism, homeostasis, development, growth, reproduction and energy metabolism. They also have profound roles in molecular and cellular mechanisms. Thus, an accurate quantitative or qualitative analysis is required for research purposes. This can be achieved by using stable isotope labeled steroid standards.

A method of choice for target or untargeted metabolomics analysis of different classes of steroid′s is Liquid Chromatography – Mass Spectrometry (LC-MS). For targeted or untargeted metabolomics overcoming ion suppression, ion variability and drifting signal are challenging aspects of analysis. Use of a deuterated steroids mixture could overcome those challenges.

Steroids standard mixture is dissolved in methanol. This mixture product is formulated for use as a concentration standard for high-throughput LC/MS metabolomic analysis.

• All deuterated steroids are dissolved in methanol and ready to use. Total vial volume is 1 ml.
• This mixture can be used for targeted and untargeted approaches.
• Ideal for LC-MS studies as internal standards.
