iTRAQ is a technique that utilizes a multiplexed isobaric chemical tagging reagent which allows multiplexing of two to eight protein samples and produces identical MS/MS sequencing ions for all eight versions of the same derivatized tryptic peptide. iTRAQ-based Proteomics Analysis Creative Proteomics offers iTRAQ protein quantification service suited for unbiased untargeted biomarker discovery. iTRAQ® is a powerful quantitative proteomics technique for broad and unbiased quantification of proteins expressed across multiple biological samples. iTRAQ generates relative quantitative proteome profiles and enables you to perform comparisons across multiple samples in a single experiment. These techniques use multiplexed isobaric mass tags to label peptide digest mixtures. iTRAQ (AB SCIEX) has 4 or 8 complementary reagents consisting of an amine reactive group (binds to N-terminal and the epsilon amino group of Lysine), a reporter group (with masses of 114-117 for the 4 plex and 113-119; and 121 for the 8 plex), and a “balance” group (keeps the tag mass at a constant 145 Da for the 4 plex and 304 Da for the 8 plex). In the present study, we utilized iTRAQ-based quantitative proteomics to analyze the protein alterations in Streptococcus pneumoniae in response to SNH treatment.

ITRAQ quantitative technology has been widely used because it can simultaneously analyze 8 samples using an 8-fold ITRAQ reagent (Wiese et al., 2007). In recent years, proteomics analyses of serum, liver, kidney, and bone exposed to fluoride have been reported (Sun et al., 2018; Wei et al., 2016, 2018). Isobaric tag for relative and absolute quantization (iTRAQ) is a mature technique widely used in proteomics which can quantify proteins based on peptide labeling and allows the identification and quantification of peptides and proteins from various samples within broad dynamic ranges of protein abundance [ 6 A coupled iTRAQ/LC–MS/MS-based approach has been applied as a powerful sensitive proteomics tool for concurrently quantifying proteins in 4- or 8-plex samples during the discovery of disease biomarkers .

For more details on NPTEL visit http://nptel.iit Speaking of iTRAQ (Isobaric Tag for Relative and Absolute Quantitation) and TMT (Tandem Mass Tag), many of us may think that they are two different quantitative proteomics techniques, but in fact… 2020-07-21 · In conclusion, iTRAQ-based proteomics analysis identified 79 proteins that interact with FASN. Four proteins (FSCN1, SIPA1, SPTBN1 or CD59) closely associated with tumor metastasis interacted with FASN and exhibited decreased expression in response to FASN silencing.
