Assay methods may generally comprise forming homogeneous assay mixtures comprising target SAM-utilizing protein, fluorescent detection analyte, and test compound, incubating, and measuring FP or TR-FRET signal emitted in order to determine a measure of test compound-SAM-utilizing protein binding. Assay mixtures comprise a SAM-utilizing protein, and a fluorescent detection analyte that binds with the SAM-utilizing protein in the absence of test compound. Assay mixtures may further comprise a test compound. Assay mixture embodiments may generate FP or TR-FRET signal properties that are a function of the inherent binding interactions of both the test compound and the detection analyte with the SAM-utilizing protein. Fluorescent detection analytes comprise a fluorophore moiety, a covalent linker moiety, and a SAM-utilizing protein ligand moiety and could be utilized in FP or TR-FRET assays to measure test compound binding.
检测方法通常包括形成均质的检测混合物,其中包括目标SAM利用蛋白、荧光检测分析物和测试化合物,孵育,并测量发射的FP或TR-FRET信号,以确定测试化合物-SAM利用蛋白结合的度量。检测混合物包括SAM利用蛋白和荧光检测分析物,在没有测试化合物的情况下与SAM利用蛋白结合。检测混合物还可以包括测试化合物。检测混合物的实施形式可以生成FP或TR-FRET信号特性,这些特性是测试化合物和检测分析物与SAM利用蛋白固有结合相互作用的函数。荧光检测分析物包括荧光团、共价连接物和SAM利用蛋白配体团,可以用于FP或TR-FRET检测来测量测试化合物的结合。
