The present invention relates to methods and compositions for detecting an interaction between a protein and a ligand, comprising: (i) binding at least one fluorescent molecular rotor to said ligand or protein; and (ii) detecting a change in fluorescence emitted by said fluorescent molecular rotor after contact of the bound fluorescent molecular rotor with the other of said ligand or protein, thereby detecting an interaction between the ligand and the protein, wherein the fluorescent molecular rotor comprises: a rotating ?-bond; an electron-donating moiety; an electron-accepting moiety; and a ?-conjugated linker.
本发明涉及一种检测蛋白质与
配体之间相互作用的方法和组合物,包括:(i)将至少一个荧光分子转子结合到所述
配体或蛋白质上;和(ii)在所述结合的荧光分子转子与所述
配体或蛋白质中的另一个接触后检测所述荧光分子转子发射的荧光变化,从而检测
配体和蛋白质之间的相互作用,其中所述荧光分子转子包括:一个旋转的π键;一个给电子的基团;一个受电子的基团;和一个π共轭连接物。
