    摘要: The present invention relates to a method of detecting biologically active substances affecting intracellular processes, an isolated DNA, a vector and a cell for use in the method. More specifically, the present invention provides a method for detecting a biologically active substance that affects intracellular processes mediated through a protein kinase or a second messenger, which comprises incubating a cell with a test substance and measuring any change caused by the test substance in the flourescence of (i) a wild-type or modified green flourescent protein (GFP) having a protein kinase recognition site, (ii) a modified GFP containing a second messenger binding domain, or (iii) a hybrid polypeptide having a wild-type or modified GFP and an attached protein kinase recognition site or a second messenger binding domain.

    摘要: The present invention relates to novel fluorescent dyes, novel fluorogenic and fluorescent reporter molecules and new enzyme assay processes that can be used to detect the activity of caspases and other enzymes involved in apoptosis in whole cells, cell lines and tissue samples derived from any living organism or organ. The reporter molecules and assay processes can be used in drug screening procedures to identify compounds which act as inhibitors or inducers of the caspase cascade in whole cells or tissues. The reagents and assays described herein are also useful for determining the chemosensitivity of human cancer cells to treatment with chemotherapeutic drugs. The present invention also relates to novel fluorogenic and fluorescent reporter molecules and new enzyme assay processes that can be used to detect the activity of type 2 methionine aminopeptidase, dipeptidyl peptidase IV, calpain, aminopeptidase, HIV protease, adenovirus protease, HSV-1 protease, HCMV protease and HCV protease.

    摘要: The invention provides monoclonal antibodies and other binding agents to human cytochrome P450 2A6 having advantageous properties, including capacity substantially to inhibit enzyme activity of human cytochrome P450 2A6 and lack of specific binding to other human cytochromes P450. The binding agents of the invention are useful inter alia in methods for screening drugs for metabolism by cytochrome P450 2A6, and in methods of measuring p450 2A6 levels in an individual relative to p450 2A6 levels in a control population.

    摘要: This invention relates to the discovery that toxicity to mustard may be evaluated by diagnostic test means disclosed herein. Upon electrophoretic separation (sodium dodocyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE)) of buffered extract of human skin cells (normal human epidermal keratinocytes (NHEK)) which had been exposed to mustard-type chemical compounds a band at approximately 50,000 to 80,000 daltons molecular weight was found. The protein band constitutes a biomarker.
