2019;13(3):e1700153. Isobaric Tag for Relative Absolute Quantitation (iTRAQ) and Tandem Mass Tags (TMT) are two similar quantitative proteomic techniques developed by AB SCIEX and Thermo Fisher, respectively. The most distinctive advantage of these two techniques is that they can label up to 10 different samples and compare the relative proteomic change through LC-MS/MS analysis. Comprehensive comparisons of quantitative proteomics techniques are rare in the literature, yet they are crucially important for optimal selection of approaches and methodologies that are ideal for a given proteomics initiative. In this study, two LC-based quantitative proteomics approaches—iTRAQ and label-free—were implemented using the LTQ-Orbitrap Velos platform. For this comparison Se hela listan på academic.oup.com To identify potential microRNA-target pairs associated with osteopetrosis, we performed a system approach including deep sequencing, iTRAQ quantitative proteomics, and bioinformatics in the peripheral blood mononuclear cells (PBMCs) taken from patients with osteopetrosis and health donors. 2007-03-16 · We then developed a quantitative strategy that comprises labeling of intact proteins by iTRAQ followed by gel electrophoresis and peptide MS/MS analyses.

As proof of principle, mixtures of five different proteins in various concentration ratios were quantified, demonstrating the general applicability of the approach presented here to quantitative MS‐based proteomics. Isobaric tags for relative and absolute quantification (iTRAQ) as a high-throughput proteomics approach are useful for the analysis of infection-associated proteins of pathogens [22–24]. Sun et al. identified 192 significantly expressed host proteins in a DTMUV-infected baby hamster kidney cell line using the iTRAQ approach.
