    • PURPOSE: A high speed multiple-unrestricted modification searching method through a mass spectrometry and a device thereof are provided to use dynamic programming algorithm based on a multi sequence tag from each a mass spectrometry spectrum according to modification alignment, thereby determining modifications about a database peptide. CONSTITUTION: MS/MS spectrum information is inputted from a mass spectrometry. A plurality of amino acid ranking tags is induced. Each of ranking tags is arranged about candidate peptides including the corresponding ranking tags in a database. Modification within the candidate peptide is identified without a limit of the number of modifications by every peptide through dynamic programming limiting a moving route according to location information of tags in a matrix. Each of the ranking tags are arranged for arrangement between ranking of the spectrum information and the candidate peptides in the matrix.

    • It is intended to provide a protein analysis method whereby proteins can be identified and the quantification data can be obtained by a convenient procedure. Namely, a protein analysis method characterized by comprising: the step of cleaving two protein-containing samples individually with restriction enzymes at specific amino acid sites to give peptide chain-containing samples; the step of modifying peptide chains contained in the peptide chain- containing samples with labeling compounds having different masses due to isotopes so as to impart different masses to the peptide chains; the step of mixing the isotope-labeled peptide chain-containing samples and fractionally quantifying the sample mixture for individual peptide chains so as to determine a content ratio; the step of selecting peptide chains to be subjected to amino acid sequence identification from the peptide chains and identifying the amino acid sequences of the peptide chains; the step of specifying proteins corresponding to the peptide chains; and the step of determining the content ratio of the thus specified proteins based on the fractional quantification data of the peptide chains. ® KIPO & WIPO 2007
