  • Patent number: 7416854
    Abstract: A method to detect the presence or amount of at least one molecule for an enzyme-mediated reaction in a multiplex luminogenic/nonluminogenic assay is provided.
    Type: Grant

  • Patent number: 7282348
    Abstract: Disclosed are a method and a corresponding kit for determining the cytotoxicity of a test agent. The method includes the steps of adding a pre-determined amount of the test agent to a vessel containing living cells in culture medium. The cells are then incubated for a pre-determined amount of time. To the cells and culture medium is then added a reagent mixture that is non-toxic to the living cells. In the preferred embodiment, the reagent mixture contains a solvent, a dye, an electron transfer agent, a substrate for a cytoplasmic enzyme having a half-life greater than two hours and NAD+. The contents of the vessel are then measured for production of the reduced state of the dye, the production of the reduced state of the dye being caused by a cytoplasmic enzyme specific for the substrate in the reagent mixture. In the preferred embodiment, the production of the reduced state of the dye is caused by lactate dehydrogenase released from dead and dying cells within the vessel.
