Splet08. apr. 2024 · LC-MS/MS-based proteomics is a powerful tool based on the amino acid sequencing of peptides by inducing their fragmentation for identifying and quantifying proteins in biological samples [ 64 ]. This technique, as well as 2-DE, are widely used in clinical medicine [ 65 ], both being successfully used for biomarker discovery [ 7 ]. Spletpred toliko dnevi: 2 · Pooled peptides were further cleaned using C18 stage tips, vacuum dried, and subjected to LC-MS/MS analysis. 2.5.3 LC-MS/MS Analysis Peptides were resuspended in 0.1% formic acid and subjected to LC-MS/MS analysis on Orbitrap Fusion Lumos connected to Ultimate 3000 RSLC nano system or Orbitrap Eclipse Tribrid mass …
SpletRaw shotgun LC-MS/MS data were searched with Proteome Discoverer (version 1.4, Thermo Scientific) using the Mascot search engine (version 2.5). Since a search space for non-human peptides can become enormous, we conducted a two-step database search strategy. Generated peak lists were first searched against the Swiss-Prot database: … SpletA major advantage of shotgun lipidomics over LC-MS analysis of lipids is that a mass spectrum displaying molecular ions of individual molecular species of a lipid class of …
Splet01. jul. 2015 · Bottom-up, shotgun proteomics is usually performed in a liquid chromatography-tandem MS (LC-MS/MS) 1 format, where nanoscale liquid chromatography is coupled through electrospray ionization to an instrument capable of measuring a mass spectrum and fragmenting the recognized precursor peaks on the chromatographic time … Splet15. apr. 2024 · LC-MS/MS analysis was performed after the two peptide samples were mixed in equal proportions (50 μL:50 μL). Peak area was calculated by MultiQuant v. 3.0 software, manually checked, and adjusted as needed.
Splet16. mar. 2015 · Because a shotgun proteomics experiment cannot regulate that the same set of peptides are identified across different LC-MS runs, the intersection of confident identifications of the three triplicate runs was taken as a ‘core peptide pool’ for each experimental set-up, i.e. total, technical and labeling.
