CELL IDENTIFICATION DEVICE AND PROGRAM
First Claim
1. An apparatus that includes a storage section and a computation section and identifies a type of a test cell based on a result obtained by performing mass spectrometry on the test cell, the apparatus characterized in thatthe storage section stores a database containing mass lists for a plurality of known cells, each of the mass lists listing ion mass values or molecular weights of constituent components of the known cell,the computation section includesa) first search means for searching the database for a test mass list which is created based from a result of the mass spectrometry and which lists ion mass values or molecular weights of constituent components of the test cell,b) classification group determination means for determining, based on a result of the search performed by the first search means, a classification group to be searched in the following search operation,c) test partial mass list creation means for creating a test partial mass list from the test mass list by deleting ion mass values or molecular weights common to the classification group determined by the classification group determination means, andd) second search means for searching, among the mass lists contained in the database, mass lists for known cells which belong to the classification group determined by the classification group determination means for the test partial mass list,wherein the second search means deletes, from the mass lists to be searched, ion mass values or molecular weights common to the classification group determined by the classification group determination means and searches the mass lists having undergone the deletion operation for the test partial mass list.

Abstract
An apparatus that identifies the type of a test cell based on a result obtained by performing mass spectrometry on the test cell includes a higher-level database, which contains mass lists that each list ion mass values of constituent components of a known cell, and a lower-level database, which contains partial mass lists that each list only strain-specific ion mass values out of the ion mass values. The higher-level database is first searched for a test mass list which is created from the result of the mass spectrometry performed on the test cell, and based on a result of the search, an organism species to be searched in the following search operation is determined. Mass values common to the organism species are subsequently deleted from the mass list for the test cell, and the mass list having undergone the deletion operation is used to search the lower-level database.
