Ribosomal protein judgement method, biological species identification method, and mass spectrometry apparatus

Abstract

Provided is a ribosomal protein judgement method, comprising: an attribution step that involves comparing observed m/z values indicated by peaks on a mass spectrum detected by mass spectrometry of a sample containing ribosomal proteins, with first calculated m/z values based on a database, and attributing at least some of the peaks thus detected to ribosomal proteins; and a presumption step that involves presuming a protein corresponding to a peak with a relative intensity from 50 to 150% relative to an approximate curve or an approximate straight line plotted with relative intensities of the peaks attributed to ribosomal proteins, to be a ribosomal protein.

Dependencies are inferred from the claim text.
