The present invention relates to methods of conducting assays for enzymatic activity on microarrays useful for the large-scale study of protein function, screening assays, and high-throughput analysis of enzymatic reactions. The invention relates to methods of using protein chips to assay the presence, amount, activity and/or function of enzymes present in a protein sample on a protein chip. In particular, the methods of the invention relate to conducting enzymatic assays using a microarray wherein a protein and a substance are immobilized on the surface of a solid support and wherein the protein and the substance are in proximity to each other sufficient for the occurrence of an enzymatic reaction between the substance and the protein. The invention also relates to microarrays that have an enzyme and a substrate immobilized on their surface wherein the enzyme and the substrate are in proximity to each other sufficient for the occurrence of an enzymatic reaction between the enzyme and the substrate.
本发明涉及在微阵列上进行酶活性测定的方法,这种方法可用于蛋白质功能的大规模研究、筛选测定和酶反应的高通量分析。本发明涉及使用蛋白质芯片检测蛋白质芯片上蛋白质样品中酶的存在、数量、活性和/或功能的方法。特别是,本发明的方法涉及使用芯片进行酶测定,其中蛋白质和物质被固定在固体支持物表面,蛋白质和物质相互靠近,足以使物质和蛋白质之间发生酶反应。本发明还涉及在其表面固定有酶和底物的微阵列,其中酶和底物相互靠近,足以使酶和底物之间发生酶反应。
