Kinase and phosphatase assays

The composite for detecting and monitoring kinase or ホスファターゼ activity, a method, and a kit are described. Peptide, a detectable portion, and a protease cutting part are typically contained in a composite. If peptide is changed by kinase or ホスファターゼ, the susceptibility over protein disassembly of peptide will change and change of the characteristic which can detect a composite will take place by it. The panel assay for determining the substrate or regulation substance of kinase or ホスファターゼ activity is also described.
