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.
Can isotopes be used for human diagnosis?
Yes, isotopes are used in humans to make diagnoses of diseases. Common ones are Th, In, and Ga, and an isotope of iodine is used in treatment of hyperthyroid conditions.
How is nitrogen used by humans?
Ammonia, nitrates, nitrites
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 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.
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.
How do you use the word isotopes in a sentence?
The medical test used isotopes.
What are laser printers used for?
They are used to support mobile labeling applications.
Is radioactive isotopes used to treat cancer.?
Yes, radioactive isotopes are largely used for the treatment of cancer.
Can isotopes be used for human diagnosis?
Yes, isotopes are used in humans to make diagnoses of diseases. Common ones are Th, In, and Ga, and an isotope of iodine is used in treatment of hyperthyroid conditions.
What is a labeling machine used for?
A labeling machine is used to dispense or apply labels to various products, container or packaging. Most of the large manufacturer company would use this for their products.
How is nitrogen used by humans?
Ammonia, nitrates, nitrites
