Stable Isotope Products for Chemical Labeling Stable isotope coded chemical tags enable researchers to perform mass spectrometric- based proteomics studies in the absence of metabolic labeling. Labeling occurs by site-specific incorporation of stable isotope labeled tags at cysteine residues or the general labeling of amines and carboxyl groups in protein samples. 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.

Differential labeling of proteins and peptides. Amino acid type selective labeling. Site-specific labeling. Random or fractional labeling. Specific protonated amino Stable isotope coding approaches alleviate these drawbacks and allow comparative drug metabolomics studies similarly to the differential proteomic techniques developed in the last decade. 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.

Using stable isotope labeling and siRNA-mediated gene silencing, we showed that A549 lung cancer cells produce NAA and its downstream … 2019-06-26 15 N-labeling. To date, most dynamics studies have been performed using uniform 15 N enrichment. 15 N is a good target to study for a variety of reasons. The necessary nitrogen needed for cell growth can be controlled by use of 15 N-enriched minimal or nutrient-rich growth media that are readily available, allowing for easy sample preparation.

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. Sources of isotopes used for labeling The simplest labeling, and also the cheapest one is 15 N, because 15 N ammonia is quite cheap. 13 C is more expensive, because it requires the synthesis (most commonly - biosynthesis) of 13 C glucose, some expression systems allow use of cheaper 13 CO 2 .
