Isotopic labeling of compounds is a non-radioactive method of labeling, provides site-specific investigation of structures, makes molecules easily detectable by mass spectrometry and NMR, maintaining the physico-chemical properties of the target molecule, and is cost-effective and easy to use. Most commonly used isotopes are 2H (D), 13C, and 15N.

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.

Here we have developed a stable isotope labeling comparative analysis of RNA digests (SIL-CARD) approach, which improves upon the original 18O/16O labeling … 2003-05-18 Cambridge Isotope Laboratories offers a complete listing of Stable Isotope Labeled Mass Spec for all your research needs.

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). Isotope labeling of biologically interesting proteins is a prerequisite for structural and dynamics studies by NMR spectroscopy. Isotopic labeling of compounds is a non-radioactive method of labeling, provides site-specific investigation of structures, makes molecules easily detectable by mass spectrometry and NMR, maintaining the physico-chemical properties of the target molecule, and is cost-effective and easy to use. Most commonly used isotopes are 2H (D), 13C, and 15N. Isotope Labeling Designing, preparing, and characterizing radio- and mass-labeled compounds 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.

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
