The present invention provides methods for the identification of target molecules that bind to ligands, particularly microRNA ligands and mimics thereof and/or microRNA target molecules and mimics thereof, with as little as millimolar (mM) affinity using mass spectrometry. The methods may be used to determine the mode of binding interaction between two or more of these target molecules to the ligand as well as their relative affinities. Also provided are methods for designing compounds having greater affinity to a ligand by identifying two or more target molecules using mass spectrometry methods of the invention and linking the target molecules together to form a novel compound.
本发明提供了一种使用质谱技术,以毫摩尔(mM)亲和力
水平,鉴定与
配体结合的靶分子的方法,特别是微RNA
配体及其模拟物和/或微RNA靶分子及其模拟物。该方法可用于确定两个或更多这些靶分子与
配体之间的结合模式以及它们的相对亲和力。本发明还提供了一种通过使用本发明的质谱技术鉴定两个或更多靶分子,并将这些靶分子连接起来形成新化合物,从而设计具有更高亲和力的
配体的方法。
