    • The present invention provides methods for assaying the activity of protein kinases or phosphatases that involve reacting the enzymes with substrate, at least a portion of which is fluorescently labeled; allowing phosphorylated substrate to bind to a solid support coated with a phosphate-binding material; and measuring the fluorescence produced by bound, labeled substrate. The invention also provides methods for identifying substances that modulate the activity of protein kinases and phosphatases that comprise reacting the enzymes with a substrate, at least a portion of which is fluorescently labeled, in the presence and absence of test compounds, allowing phosphorylated substrate to bind to a solid support coated with a phosphate-binding material, measuring the fluorescence produced by bound, labeled substrate, and comparing the fluorescence from reactions carried out in the presence and absence of test compounds.
    • 本发明提供了用于测定蛋白激酶或磷酸酶的活性的方法,其涉及使酶与底物反应,其中至少一部分被荧光标记; 允许磷酸化底物结合涂覆有磷酸盐结合材料的固体支持物; 并测量由结合的标记底物产生的荧光。 本发明还提供了用于鉴定调节蛋白激酶和磷酸酶的活性的物质的方法,其包括在存在和不存在测试化合物的情况下使酶与底物反应,其中至少一部分被荧光标记,允许磷酸化底物结合 包被磷酸盐结合材料的固体支持物,测量由结合的标记底物产生的荧光,并比较在存在和不存在测试化合物的情况下进行的反应的荧光。
