Displaying 4 results of Spermine Stable Isotopes Spermine Stable Isotopes are a set of isotopically labeled compounds that are used in scientific research to study the biochemical and physiological functions of spermine, a natural polyamine found in living cells. These isotopes are chemically identical to the non-labeled compounds, but contain a stable isotope of carbon or nitrogen, which allows for precise quantification and tracking of spermine metabolism in cells and tissues. Spermine Stable Isotopes have a wide range of applications in fields such as cancer research, neurobiology, and drug development.
