摘要： It is an object of the present invention, when determining and identifying an amino acid sequence of a peptide using MS, to obtain additional information from the MS for evaluating validity of an amino acid sequence in a candidate list outputted from an identifying engine. The present invention provides a method of testing an amino acid sequence inferred by searching a peptide-related database based on peptide mass information and/or peptide modification information obtained through mass spectrometry on a peptide, the method comprising the steps: (1) calculating a theoretical value of an isotopic ratio for the peptide from the inferred amino acid sequence and/or the peptide modification information; (2) measuring a measured value of the isotopic ratio for the peptide from the peptide mass information; and (3) comparing the theoretical value and the measured value, and evaluating validity of the inferred amino acid sequence from differences between the theoretical value and the measured value.

摘要： The present inventor has established protein abundance index (PAI, π) to determine the protein contents in a protein mixture solution using nanoLC-MSMS data. Digested peptides were analyzed by nanoLC-MS/MS and the obtained results were applied to a Mascot protein identification algorism based on tandem mass spectra. For absolute quantitation, PAI was converted to exponentially modified PAI (EMPAI, m π), which is proportional to protein contents in the protein mixture. EMPAI was successfully applied to comprehensive protein expression analysis and performed a comparison study between gene and protein expression in an HCT116 human cancer cells. Accordingly, the present invention provides a method and a computer program for quantifying the protein contents based on the protein abundance index.
