LABELING AGENT AND AMINO ACID SEQUENCE USING SAME, AND METHOD FOR PERFORMING SIMULTANEOUS QUANTITATIVE ANALYSIS OF MULTIPLE PROTEINS

摘要

Disclosed is a compound that uses a hydrogen isotope that is capable of reducing costs for labeling agent synthesis and also simultaneously quantifying multiple samples. The present invention also relates to a novel method of quantitatively analyzing protein and peptide analyzers of mutually different quantities using a labeling agent, wherein after the labeling agent is coupled to the analyzer, only a portion of the labeling agent is removed through tandem quantitative analysis, and quantitative analysis is performed using a y-type fragment ion of a large quantity including the analyzer.
