Abstract

See full text

A method for analyzing a binding ability of protein to a compound, comprising the steps of (a) fractionating a first group of isotope-labeled proteins into plural fractions using a carrier having the compound immobilized thereon; (b) fractionating a second group of proteins into one or plural fractions using a carrier having the compound immobilized thereon; (c) adding an amount of at least one fraction obtained in step (b) to each of the fractions obtained in step (a); (d) analyzing the fractions obtained in step (c) with mass spectrometry; and (e) based on the mass spectrometry information, obtaining, regarding each fraction, an intensity ratio between a peak derived from a protein in the fraction obtained in step (a) and a peak derived from a protein in the fraction obtained in step (b), and comparing degrees of the binding ability of the plural kinds of proteins to the compound.
