    • Disclosed herein is a method for detecting a compound-protein interaction, involving: (a) providing a compound library in which each member of the compound library is immobilized on a solid support; (b) contacting each member of the immobilized compound library in a single reaction chamber with each member of a protein-nucleic acid fusion library under conditions which allow the formation of compound-fusion complexes; (c) isolating the immobilized compound-fusion complexes; and (d) detecting a compound-fusion complex as an indication that the protein of the fusion interacts with the compound. In preferred embodiments, the protein is identified by reading the nucleic acid portion of the fusion, and the compound is identified by reading a detectable tag bound to either the compound or the solid support.
    • 本文公开了一种用于检测化合物 - 蛋​​白质相互作用的方法,包括:(a)提供化合物文库,其中化合物文库的每个成员固定在固体支持物上; (b)在允许形成化合物 - 融合复合物的条件下,使单个反应室中的每个成员与蛋白质 - 核酸融合文库的每个成员接触; (c)分离固定的化合物 - 融合物; 和(d)检测化合物 - 融合复合物作为融合蛋白质与化合物相互作用的指示。 在优选的实施方案中,通过读取融合物的核酸部分来鉴定蛋白质,并且通过读取与化合物或固体支持物结合的可检测标签来鉴定该化合物。
