Title: Stable-Isotope Labeling for Protein Quantitation by Mass Spectrometry VOLUME: 7 ISSUE: 2 Author(s):Kolbrun Kristjansdottir and Stephen J. Kron Affiliation:Ludwig Center for Metastasis Research, 924 E. 57th St., Chicago, IL 60637, USA. Quantitative mass spectrometry has emerged as a powerful tool for biological research. Quantitative mass spectrometry typically utilizes proteins labeled with heavy stable isotopes, e.g. 15N, 18O, or 13C. Labeled or “heavy” peptides maintain the same chemical characteristics as unlabeled or “light” peptides and co-elute into A discussion on how mass spectrometry works and what isotopes are, as well as how to represent isotopes. Herein, we reported the comprehensive profiling of fecal metabolome of mice by an integrated chemical isotope labeling combined with liquid chromatography–mass spectrometry (CIL-LC-MS) analysis. The metabolites are categorized into several submetabolomes based on the functional moieties (i.e., carboxyl, carbonyl, amine, and thiol) and then analysis of the individual submetabolome was performed. AbstractEven with the advent of high throughput methods to detect modified ribonucleic acids (RNAs), mass spectrometry remains a reliable method to detect, characterize, and place post-transcriptional modifications within an RNA sequence.

Any technique in measuring the difference between isotopomers can be used. The two primary methods, nuclear magnetic resonance (NMR) and mass spectrometry (MS), have been developed for measuring mass isotopomers in stable isotope labeling. Proton NMR was the first technique used for 13 C-labeling experiments.

The protein N-terminal sequence is essential for protein identification and confirmation of the removal of N-terminal methionine or signal peptides. Without special labeling, it is difficult to distinguish the protein N-terminus from lots of peptides derived by enzymatic digestion by mass spectrometry (MS).
