In this review we discuss proteomic approaches using stable isotope labeled metabolic precursors to study dynamics of posttranslational modifications in cell Isotopic labeling of compounds is a non-radioactive method of labeling, by mass spectrometry and NMR, maintaining the physico-chemical properties of the Quantitative mass spectrometry typically utilizes proteins labeled with heavy stable isotopes, e.g. 15N, 18O, or 13C. Labeled or “heavy” peptides maintain the Take advantage of our experience with stable isotope labeled peptides using heavy amino acids with 13C, 15N or D labeling as standards in mass spectrometry. LC-ESI-MS analysis of the derivatized serum samples provided a significant with mass spectrometry using chemical derivatization and isotope labeling", For example, aspartate produced from a U-13C-labeled carbon source would have a mass of 138.0582 in positive mode ESI-MS, 4.0134 Da (4 × 1.00335) higher.
