Mass spectrometer (MS)-based methods to quantify key biological components are based on the improved sensitivity, specificity and throughput of the LC-MS/MS. Stable isotope-labeled internal standards are important features that help to optimize the accuracy of the method and provide perfect results.

Steroids and hormones play an important role in metabolic processes and are widely used in pharmaceutical fields. Their intricate reactivity profile and structural similarities make their study intensely challenging. Stable isotope labeled steroids and hormones can ease the difficulties of identification, differentiation, and analysis. The labeled compounds can be used in a wide range of research areas, such as environmental contamination resulting from hormone excretion and quantification of therapeutic agents (like corticosteroids). MS-based methods combined with stable isotope labeled steroids and hormones can accelerate your research.

As a supplier of isotope labeled products in the industry, Creative Proteomics offers more than 10,000 products labeled with different isotopes of carbon, hydrogen, nitrogen, and oxygen. Creative Proteomics supplies stable isotope labeled steroids and hormones, including hydroxyprogesterone, methoxyestradiol, androstene, and so on. Custom synthesis steroids and hormones are also available to meet our customers’ research needs.
