    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.

    摘要: According to the present invention, phosphorylated peptides and/or phosphorylated proteins are specifically separated. A sample containing a phosphorylated peptide and/or a phosphorylated protein is supplied to a separation unit filled with a metal oxide in the presence of an aliphatic hydroxycarboxylic acid. Upon separation of a phosphorylated peptide and/or a phosphorylated peptide with the use of a separation unit filled with a metal oxide, adsorption of carboxylic acid to an acidic peptide can be prevented in the presence of aliphatic hydroxycarboxylic acid. In addition, aliphatic hydroxycarboxylic acid does not inhibit adsorption of a phosphorylated peptide and a phosphoric acid group in the phosphorylated peptide to a metal oxide.
