  • Patent number: 6548266
    Abstract: An assay system is provided for detecting the enzymatic activity of a phosphorylation enzyme. The enzyme may be a phosphatase or protein kinase. The substrate for the enzyme is immobilized on a solid support via covalent or non-covalent binding through a signal enhancing polymer. The immobilized substrate provides an enhanced signal to background ratio when compared to a substrate in solution. The methods are easily adapted to high throughput screening systems.
