Isotope labeling is the introduction of isotopes into the structure of a molecule for the purpose of tracing, studying, or labeling specific properties of the molecule. Isotopes are similar elements with the same number of nuclei in an atom but different masses, and have almost identical chemical properties. By introducing isotopes, it is possible to gain a deeper understanding of a molecule's behavior by determining its involvement in a reaction. Common isotopes include hydrogen isotopes (deuterium and hydrogen), carbon isotopes (12C and 13C), oxygen isotopes (16O and 18O), nitrogen isotopes (14N and 15N), and phosphorus isotopes (31P and 32P).
A class of atoms with the same number of protons and different numbers of neutrons in the nucleus are called isotopes, which are in the same position on the periodic table and can be categorized into stable and radioactive isotopes. The nucleus of a radioactive isotope is unstable, and it decays into another isotope by spontaneously emitting particles. The isotopes that are not radioactive are called stable isotopes, part of which are stable products formed by the decay of radioactive isotopes, called radiogenic isotopes, and part of which are natural stable isotopes that have remained stable since nuclear synthesis. Stable isotopes are safer, non-polluting and easier to control than radioisotopes, and are widely used in research in geology, ecology, medicine, agriculture and other fields.
Isotope labeling is a technique commonly used in molecular research involving the introduction of isotopes into the structure of molecules in order to trace, label, or study the properties, metabolic pathways, and interactions of those molecules. In nucleic acid research, isotope labeling is commonly used to track the biological behavior of DNA or RNA molecules.
