GLYCAN STRUCTURE ANALYZER AND GLYCAN STRUCTURE ANALYSIS PROGRAM

摘要

In a glycan structure analyzer according to one mode, a plurality of tabs for setting analysis conditions includes a dedicated tab for the setting of the conditions concerning a chemical modification specific to the linkage type of sialic acids, allowing a user to select major chemical modification agents. When one of those agents is selected, the mass change for each linkage type is automatically set. When using a chemical modification other than the preset ones, the user can input a numerical value of the amount of mass change for each linkage type. In an analysis, theoretical m/z values of a plurality of glycan structure candidates having different m/z values depending on the linkage type corresponding to one chemical modification are simultaneously compared with the m/z values of measured ion peaks.
