Displaying 22 results of Progesterone Stable Isotopes Progesterone stable isotopes are isotopes of the hormone progesterone that have a stable atomic nucleus. These isotopes are used in research studies to investigate the metabolism, distribution, and excretion of progesterone in the body. By using stable isotopes, researchers can trace the pathways of progesterone and gain a better understanding of its biological function. Additionally, progesterone stable isotopes have potential applications in clinical diagnostics and therapeutic monitoring.
