In the present study, we utilized iTRAQ-based quantitative proteomics to analyze the protein alterations in Streptococcus pneumoniae in response to SNH treatment. A novel, MS-based approach for the relative quantification of proteins, relying on the derivatization of primary amino groups in intact proteins using isobaric tag for relative and absolute quantitation (iTRAQ) is presented. Due to the isobaric mass design of the iTRAQ reagents, differentially label … ITRAQ quantitative technology has been widely used because it can simultaneously analyze 8 samples using an 8-fold ITRAQ reagent (Wiese et al., 2007).

diseases utilizes differential-display proteomics, mass spectrometry, iTRAQ, protein arrays, MALDI-based tissue imaging, and computational proteomics.

Bei iTRAQ (isobaric Tags for Relative and Absolute Quantitation) handelt es sich um eine experimentelle Methode aus dem Bereich der Proteinanalytik und Proteomik. Sie dient dazu, verschiedene Proteine und Peptide per Massenspektrometrie gemeinsam zu quantifizieren . Omics Technologies is the leader in state-of-the-art proteomics and genomics research and at the forefront of personalized healthcare development. We are providing our patented technologies in targeted proteomics, qualitative and quantitative proteomics, and genomics NGS from any biological sample. 2019-07-31 · Mol Cell Proteomics.

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.
