    • The invention provides an assay system for detecting a molecule that interacts with a membrane channel, the assay system including cell membranes including one or more membrane channels; support bodies including scintillant and a coupling agent that associates with the cell membrane; a ligand that is selected to bind the membrane channel, the ligand including a scintillant-activating label. According to the invention, association of the support bodies with the cell membrane and binding of the ligand to the membrane channel results in emission from the scintillant of the support bodies, and, in the presence of a test molecule that interacts with the membrane channel, the emission from the scintillant of the support bodies changes. Methods of identifying a molecule that interacts with a cell membrane channel are also described.
    • 本发明提供了一种用于检测与膜通道相互作用的分子的测定系统,该测定系统包括包含一个或多个膜通道的细胞膜; 支持体,包括闪烁体和与细胞膜缔合的偶联剂; 被选择以结合膜通道的配体,该配体包括闪烁体激活标记。 根据本发明,支持体与细胞膜的结合和配体与膜通道的结合导致来自支持体的闪烁体的发射,并且在与膜通道相互作用的测试分子的存在下, 来自支撑体的闪烁体的发射变化。 还描述了鉴定与细胞膜通道相互作用的分子的方法。
