What is TMT-Based Peptidomics Analysis?

Our esteemed service, TMT-based peptidomics analysis, epitomizes the paradigmatic approach to quantitative proteomics, harnessing the transformative power of tandem mass tags (TMT) to annotate peptides for the purpose of relative quantification. This sophisticated technique involves the endowment of peptides from diverse samples with distinctive isobaric mass tags, which seamlessly facilitate the simultaneous analysis of multiple samples within a solitary experiment. In the realm of TMT-based peptidomics Analysis, samples undergo an intricate preparation process, involving the enzymatic cleavage of proteins into peptides. These peptides then undergo labeling with TMT reagents, comprised of a salient reporter ion and a meticulously calibrated mass-balancing entity. The TMT reagents form an indissoluble bond with the amino groups of the peptides, thereby incorporating the reporter ions into the peptides. Each TMT reagent possesses an exclusive mass tag, endowing the process with the ability to simultaneously accommodate up to 10 diverse samples in a single experiment. TMT-based peptidomics analysis bestows manifold advantages over traditional label-free quantification methods. It empowers researchers to engage in high-throughput and multiplexed quantification of peptides from numerous samples, imbuing their experimental endeavors with enhanced efficiency. Furthermore, the utilization of isobaric tags effectively mitigates the impact of sample discrepancies and experimental biases, engendering quantitative results distinguished by their remarkable accuracy and reproducibility.

Our TMT Isobaric Tags

The TMT isobaric tags, also known as Tandem Mass Tags, are a set of chemically identical mass spectrometry tags that are used for quantitative proteomics analysis. Here is a list of commonly used TMT isobaric tags.

• TMT-126
  This tag has a mass of 126 Daltons and is typically used to label the reference or control sample in a TMT experiment.
• TMT-127
  This tag has a mass of 127 Daltons and is used to label the first experimental sample in a TMT experiment.
• TMT-128
  This tag has a mass of 128 Daltons and is used to label the second experimental sample in a TMT experiment.
• TMT-129
  This tag has a mass of 129 Daltons and is used to label the third experimental sample in a TMT experiment.
• TMT-130
  This tag has a mass of 130 Daltons and is used to label the fourth experimental sample in a TMT experiment.
• TMT-131
  This tag has a mass of 131 Daltons and is used to label the fifth experimental sample in a TMT experiment.

These TMT isobaric tags allow for the multiplexed labeling of up to 6 different samples, which can then be combined and analyzed together in a single mass spectrometry experiment. The relative abundance of each peptide in the different samples can be determined by comparing the intensities of the reporter ions generated during fragmentation.
