A method for analyzing a structural affinity relationship between plural kinds of proteins and a compound, comprising the steps of (a) using a compound-immobilized carrier to purify plural kinds of proteins bound to the compound on the carrier, from a group of isotope-labeled proteins; (b) using a compound-immobilized carrier to purify plural kinds of proteins bound to the compound on the carrier, from a group of proteins brought into contact with a compound beforehand; (c) mixing the proteins obtained in step (a) and step (b); (d) analyzing the mixture obtained in step (c) with mass spectrometry; (e) identifying each of plural kinds of proteins based on information obtained by the mass spectrometry; and (f) obtaining an intensity ratio between a labeled peak and a non-labeled peak of each protein, thereby quantitating an affinity ratio of the compound to each protein.
一种分析多种蛋白质与化合物之间结构亲和力关系的方法,包括以下步骤 (a) 使用化合物固定载体,从一组同位素标记的蛋白质中纯化出载体上与化合物结合的多种蛋白质; (b) 使用化合物固定载体,从一组事先与化合物接触的蛋白质中纯化出载体上与化合物结合的多种蛋白质;(c) 混合在步骤(a)和步骤(b)中获得的蛋白质; (d) 用质谱分析在步骤(c)中获得的混合物; (e) 根据质谱分析获得的信息,识别多种蛋白质中的每一种;以及 (f) 获得每种蛋白质的标记峰和非标记峰之间的强度比,从而量化化合物与每种蛋白质的亲和力比。
