What are the purposes of isotope labeling?
Isotopes are variants of a particular chemical element which differ in neutron number, although all isotopes of a given element have the same number of protons in each atom. Isotope Variation Analysis (detection of adulteration in food products or the geographic origins of products using isoscapes) and Isotopic substitution (to determine the mechanism of a chemical reaction via the kinetic isotope effect) are the most frequently used application for isotopes. Another common application for isotope is isotopic labeling, the use of unusual isotopes as tracers or markers in chemical reactions. Normally, atoms of a given element are indistinguishable from each other. However, by using isotopes of different masses, even different nonradioactive stable isotopes can be distinguished by mass spectrometry or infrared spectroscopy. For example, in 'stable isotope labeling with amino acids in cell culture (SILAC)' stable isotopes are used to quantify proteins. If radioactive isotopes are used, they can be detected by the radiation they emit (this is called radioisotopic labeling).
What are some of the roles of isotopes?
- Isotopes are used as sources of radiation in medicine, sterilization, nondestructive control, etc.- Isotopes can be used as tracers- Isotopes can be used as energy source- Isotopes are used for radioactive dating- Isotopes are used in chemical analysis- Isotopes are used in many instruments- Isotopes are used as source of nuclear energy in bombs and nuclear reactorsetc.
Is radioactive isotopes used to treat cancer.?
Yes, radioactive isotopes are largely used for the treatment of cancer.
What are Radioactive isotopes used for?
Some examples are deuterium and tritium which are radioactive isotopes of hydrogen.
Describe two ways that radioactive isotopes are used in biomedical research?
radioactive elements, tracers, are used in molecular research to investigate the movement of atoms and molecules through a biological system. At various intervals the movement of the radioactive atoms can be traced using photographic film.
What stable isotopes are used in labeling peptides?
Stable isotopes used in labeling peptides may include 2H, 15N & 13C, respectively, or a combination of 15N & 13C.Source: a passage named Stable Isotope Labeled Peptideson the website of Creative Peptides.

What are the uses of isotopes in technology?
Isotopes are used in technology for various purposes, such as in medical imaging (e.g. using radioactive isotopes for PET scans), radiometric dating of materials, tracing the source of pollutants in the environment, and enhancing the efficiency of industrial processes (e.g. isotopic labeling in research and development).
What is the difference between phosphorus 31p and 32p?
Phosphorus-31 (31P) is a stable isotope of phosphorus that is commonly used in nuclear magnetic resonance (NMR) spectroscopy, while phosphorus-32 (32P) is a radioactive isotope of phosphorus commonly used in biological research for labeling and tracking DNA and proteins. The main difference is the stability of the isotopes, with 31P being stable and 32P being radioactive.

How isotopes can be used to study biological processes?
Isotopes can be injected into a person in order to make MRI / x-ray scans more accurate. When they inject an isotope into you (like say an iodine isotope) they can see exactly where that isotope goes throughout your body (through the blood vessels if injected or through your gastrointestinal tract if swallowed).
Used to label DNA and protein in experiments?
Fluorescent dyes are commonly used to label DNA and protein in experiments. These dyes emit light when exposed to specific wavelengths of light, allowing for visualization and analysis of the labeled molecules. Additionally, radioactive isotopes can also be used for labeling, but they may pose safety and disposal challenges.
What are the usages of isotope labeled peptides?
In order to understand the dynamics of molecules in metabolic pathways, it is necessary to establish a method of tracking them. In the past, chemical labeling was the first attempt to this, however, chemical labeling has the disadvantage that the chemical properties of labeled metabolites differ from those of normal metabolites. This problem is solved by using isotopes for labeling metabolites of interest. Isotopes are atoms with the same number of protons but a different number of neutrons in their nuclei. Recall that the chemical properties of an element are a consequence of its electron configuration, which, in turn, is determined by its atomic number, not its atomic mass. The metabolic destiny of a specific atom in a metabolite can, therefore, be elucidated by isotopically labeling that position and following its progress through the metabolic pathway.The most common isotopes used in protein research are: 13C and 31P (detected by NMR techniques), and 3H, 14C, and 32P, that emit beta particles and the methods most commonly used in biochemical research for tracking isotopes are: proportional counting (by the use of Geiger counting), liquid scintillation counting, and autoradiography.
How are stable isotopes used in medicine?
Stable isotopes are used as tracers.
What is the relationshio between 31P 32P 33P in chemistry?
They are different ISOTOPES of phosphorus(P) They are different isotopes , because they have different atomic masses. This is owed to the fact that different isotyopes have different numbers of Neutrons.
How are radioactive isotopes different from isotopes?
Both isotopes and radioactive isotopes are pretty much the same but radioactive isotopes are better because it can be used to make medicine.
A radioactive element is sometimes used to trace the pathway of chemical reactions in the cell If newly synthesized proteins are radioactive the radioactive element used could be?
The radioactive element used to trace the pathway of chemical reactions in cells for newly synthesized proteins is typically sulfur-35 (35S) or carbon-14 (14C). These isotopes are incorporated into proteins during synthesis, allowing researchers to track their movement and interactions within the cell.
