This review describes a selection of methodological improvements in the use of stable isotopes labeling in combination with MS to detect drug metabolites. Using tandem in situ monitoring and isotope-labeled solids, we reveal that mechanochemical ball-milling overcomes inherently slow solid-state diffusion through continuous comminution and growth of milled particles.

Stable isotope labeling with amino acids in cell culture (SILAC) is a powerful method to identify and quantify relative differential changes in complex protein samples. This approach entails the in vivo metabolic incorporation of 'heavy' 13 C- or 15 N-labeled amino acids into proteins followed by mass spectrometry (MS) for the accelerated and comprehensive identification, characterization and Metabolic labeling, also referred to as biosynthetic labeling, relies on simple organisms, which are able to incorporate stable isotope labeled nutrients into their biomolecules. The first studies were conducted in bacteria such as Escherichia coli , where growth media with a single carbon or nitrogen source were used. The state-of-the-art isotope-labeling schemes commonly employed for NMR investigations of high-molecular-weight proteins utilize selective incorporation of protons and 13C isotopes into methyl groups of Ileδ1, Leuδand Valγside chains in a highly deuterated environment (commonly referred to as “ILV labeling”) providing a large number of high-quality probes for NMR studies of protein structure and dynamics. 2009-03-19 · Stable isotope incorporation at the peptide level using dimethyl labeling is a reliable, cost-effective and undemanding procedure that can be easily automated and applied in high-throughput We found that 4 h of incubation was optimum for heavy isotope labelling and MALDI-TOF MS could accurately detect the resistant isolates within 5 h.
The principle of tracking the passage of an isotope is to replace the specific atoms of the target molecule by their isotope because the difference between the isotope and the original atoms is relatively easily
Isotopic labeling is used to monitor the fate of a molecule or a fragment thereof through the use of detection methods that specifically distinguish the isotope used against a natural abundance background. There are many applications for the specific labeling of molecules with radioactive or stable isotopes. BOC Sciences provides wide range of services such as custom radioisotope and stable isotope labeling to support your regulatory, development or research programs. As one of the world’s leading radio-labeling groups we have a reputation for excellence in synthetic chemistry enabling us to carry out the most challenging synthetic projects.

This putative identification is corroborated by mass spectrometric fragmentation, isotope labeling, and a gene silencing experiment. Using stable isotope labeling and siRNA-mediated gene silencing, we showed that A549 lung cancer cells produce NAA and its downstream metabolite and neuropeptide NAAG (Fig. 5).
In addition to radiolabeling proteins in solution, radioisotopes have been incorporated into cytosolic Fundamentals of protein and cell interactions in biomaterials. H.P. Felgueiras, Radiolabeling is one of the Biophysical Techniques for Structural To carry out these studies, stable isotope labeling techniques have been effectively used by drug metabolism scientists and toxicologists in order to gain better understanding of the drugs' disposition, bioavailability and toxicity in in vivo studies. We specialize in custom synthesis of labeled compounds, evaluating the type and position of the label, level of isotopic enrichment, and formulation, depending on the intended use of the compound. From metabolites to carbon nanoparticles, our team has expertise with a wide variety of compounds.

Applied Radiation and Isotopes. 64 (8): 901–5. Isotopic labeling (or isotopic labelling) is a technique used to track the passage of an isotope (an atom with a detectable variation in neutron count) through a reaction, metabolic pathway, or cell. The reactant is 'labeled' by replacing specific atoms by their isotope. The reactant is then allowed to undergo the reaction. Isotopic-type stable isotope labeling methods, such as isotope-coded affinity tags (ICAT) and isotope-coded protein label (ICPL), quantify peptides at the MS level, while isobaric types, such as isobaric tags for relative and absolute quantitation (iTRAQ) and tandem mass tags (TMT), allow the mass spectrometer to generate and acquire differential isotopic reporting peaks at the tandem mass spectrometry (MS/MS) level after collision-induced dissociation (CID).
