Heavy stable isotope labels can be introduced at different st ages in the sample trea tment protocol. Below, A variety of stable isotope labeling techniques have been developed and used in mass spectrometry (MS)-based proteomics, primarily for relative quantitation of changes in protein abundances between two compared samples, but also for qualitative characterization of differentially labeled proteomes. 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). The method consists of three steps: ( i ) enzymatic digestion in H216O or isotopically enriched H218O to label individual pools of differentially phosphorylated proteins; ( ii ) affinity selection of phosphopeptides from the combined digests by immobilized metal-affinity chromatography; and ( iii ) dephosphorylation with alkaline phosphatase to allow for quantitation of changes of phosphorylation by matrix-assisted laser desorption ionization time-of-flight mass spectrometry. mass spectrometry (MS). The second is a more recently developed technique based on stable isotope tagging of proteins and auto-mated peptide MS/MS 1–3.To date, neither method has succeeded in IsoCor is a scientific software dedicated to the correction of mass spectrometry (MS) data for naturally occuring isotopes.

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. Here we have developed a stable isotope labeling comparative analysis of RNA digests (SIL-CARD) approach, which improves upon the original 18O/16O labeling
