Support for Top - down Proteomics
Top-down proteomics is a revolutionary application for the identification and characterization of protein, known to be one of the most complicated and challenging issues in biology. In top-down proteomics, the quality and speed of the data warehouse is very important, as high accuracy results are returned by a database search. ProSight Warehouse fills the critical role as the data warehouse for...
متن کاملNeutron-Encoded Mass Signatures for Quantitative Top-Down Proteomics∥
The ability to acquire highly accurate quantitative data is an increasingly important part of any proteomics experiment, whether shotgun or top-down approaches are used. We recently developed a quantitation strategy for peptides based on neutron encoding, or NeuCode SILAC, which uses closely spaced heavy isotope-labeled amino acids and high-resolution mass spectrometry to provide quantitative d...
متن کاملOnline Hydrophobic Interaction Chromatography-Mass Spectrometry for Top-Down Proteomics.
Recent progress in top-down proteomics has led to a demand for mass spectrometry (MS)-compatible chromatography techniques to separate intact proteins using volatile mobile phases. Conventional hydrophobic interaction chromatography (HIC) provides high-resolution separation of proteins under nondenaturing conditions but requires high concentrations of nonvolatile salts. Herein, we introduce a s...
متن کاملMass graphs and their applications in top-down proteomics
Although proteomics has made rapid progress in the past decade, researchers are still in the early stage of exploring the world of complex proteoforms, which are protein products with various primary structure alterations resulting from gene mutations, alternative splicing, post-translational modifications, and other biological processes. Proteoform identification is essential to mapping proteo...
متن کاملEfficient Interpretation of Tandem Mass Tags in Top-Down Proteomics
Mass spectrometry is the major analytical tool for the identification and quantification of proteins in biological samples. In so-called top-down proteomics, separation and mass spectrometric analysis is performed at the level of intact proteins, without preparatory digestion steps. It has been shown that the tandem mass tag (TMT) labeling technology, which is often used for quantification base...
