Radiolabeling is a process used in chemical synthesis and molecular biology to attach a radioactive isotope to a molecule. This technique is used to study the metabolism, distribution, and binding properties of the molecule within a living organism or in vitro.

Radiolabeling involves incorporating a radioactive nuclide into a molecule through chemical synthesis or bioconjugation methods. The most commonly used radioactive isotopes for labeling include carbon-14 (14C), tritium (3H), and iodine-125 (125I). Each isotope has unique properties and decay characteristics that make it suitable for specific applications.

The primary purpose of radiolabeling is to facilitate the detection and tracking of a molecule in various biological systems. Techniques such as scintillation counting, autoradiography, and flow cytometry allow researchers to detect and quantify the levels of the radiolabeled molecule within a sample. In addition to providing information on the molecule's behavior, radiolabeling enables the study of biological processes, such as protein-ligand interactions, enzyme kinetics, and receptor binding.

Radiolabeling is a versatile technique that has applications in various fields, including pharmaceutical research, biomedical diagnostics, and basic scientific research. However, it requires specialized equipment and safety precautions owing to the hazardous nature of the radioactive isotopes involved. Researchers must adhere to strict protocols and regulations when working with radiolabeled compounds to ensure safe handling and disposal of the materials. By understanding the principles and applications of radiolabeling, scientists can gain valuable insights into the properties and behavior of molecules at the molecular level.
