The Pierce TMT11plex Yeast Digest Standard consists of four congenic strains of Saccharomyces cerevisiae (a parental line, BY4741, and three lines lacking the non-essential proteins Met6, His4, or Ura2) labeled in triplicate (knock-out strains) or duplicate (parental strain) with TMT11-plex label reagents. The knock-out strains are used in combination with the parental strain to enable comparison of peptide and protein abundance for quantitation. Pierce TMT11plex Yeast Digest Standard:
• Convenient—ready-to-use lyophilized powder pre-labeled with TMT11plex reagents
• Quality—yeast strains verified for genotype, equimolar mixing of the TMT-labeled strains
• Quantitative—measure the quantitative precision of TMT reporter ions for 11 channels
• Diagnostic—excellent QC assay tool for protein quantitation using TMT on LC-MS/MS instruments
Quantitative proteomic strategies using TMT reagents enable multiplexing and precise measurement of protein abundance. Successful execution of TMT quantitation includes optimized chromatography, mass spectrometry (MS), and data analysis. A critical parameter for success in this workflow is the ability to consistently detect TMT fragment ions across 11 channels for multiplexing. Our TMT11plex Yeast Digest standard has been specifically designed to assess LC-MS/MS system performance for TMT quantitation, MS method optimization and system validation. For method development, TMT11plex Yeast Digest Standard can be used to measure the accuracy, precision, and dynamic range of different mass spectrometry approaches. These standards can help optimize offline fractionation, chromatography, mass spectrometry acquisition, and data analysis settings. Multifunctional applications using this standard reduces inter-experiment variability to provides reproducible TMT quantitation.
