Steroids andHormones
For Qualification and Quantitation

Steroids and hormones play vital roles in the regulation of a diverse array of cellular functions and physiological processes. These pertain
to development, reproduction, homeostasis, and metabolism, among others. Accurate quantification of this compound class is essential
for basic and clinical translation research. This can be achieved by spiking an isotopically labeled steroid standard(s) into a sample ofinterest, such as plasma or urine, with measurement performed by an MS- or NMR-based approach.
CIL offers a variety of stable isotope-labeled and unlabeled steroids and hormones. These are available in different labeling
patterns in their neat and /or solution forms. See isotope.com for a complete listing and unit sizes.
