What is meant by radioactive tagging?
A radioactive isotope that is incorporated into a chemical or organic material to allow its detection in metabolic or chemical processes. Synonym: radiolabel.
What is radioisotope labeling?
Radioisotopic labeling is a technique for tracking the passage of a sample of substance through a system. The substance is “labeled” by including radionuclides in its chemical composition. When these decay, their presence can be determined by detecting the radiation emitted by them.
What is a suitable definition for radioisotopes?
An unstable form of a chemical element that releases radiation as it breaks down and becomes more stable. Radioisotopes may occur in nature or be made in a laboratory. In medicine, they are used in imaging tests and in treatment. Also called radionuclide.
What is radioactive tagging used for?
A radioactive tracer, radiotracer, or radioactive label, is a chemical compound in which one or more atoms have been replaced by a radionuclide so by virtue of its radioactive decay it can be used to explore the mechanism of chemical reactions by tracing the path that the radioisotope follows from reactants to products …
What are radioactive tracers and examples?
Examples of Radioactive Tracers Usually, the isotopes chosen for use as radioactive tracers have a short half-life. Examples of commonly used radioactive tracers include tritium, carbon-11, carbon-14, oxygen-15, fluorine-18, phosphorus-32, sulfur-35, technetium-99, iodine-123, and gallium-67.
What are radiolabeling techniques?
Radiolabeling is a technique used to track the passage of a molecule that incorporates a radioisotope through a reaction, metabolic pathway, cell, tissue, organism, or biological system. The reactant is ‘labeled’ by replacing specific atoms by their isotope. Radiolabeling is not necessary for some applications.
What are radiolabeled drugs?
Radiolabeling involves substituting one or more atoms belonging to your investigational drug compound, with a radioisotope. This allows you to monitor the in vivo behavior of a drug, tracing its distribution within the body.
What is radioisotope used for in medicine?
Radioisotopes are an essential part of medical diagnostic procedures. In combination with imaging devices which register the gamma rays emitted from within, they can be used for imaging to study the dynamic processes taking place in various parts of the body.
