Stable isotopes do not undergo radioactive decay and are used in histology for various labeling techniques. Unlike radioactive isotopes, stable isotopes such as carbon-13 (¹³C) and nitrogen-15 (¹⁵N) are non-radioactive and can be detected using mass spectrometry or nuclear magnetic resonance (NMR) spectroscopy. These techniques allow for the study of metabolic processes without the potential hazards associated with radioactivity.
