  • Process for reducing interferences in luciferase enzyme assays
    Patent number: 7829280
    Abstract: A method of conducting a biochemical assay that allows for a reduction of assay interferences. The method comprises treating a mixture of cell sample and cell constituents solubilizing agent, with an insoluble agent prior to conducting the assay. There is also provided a device as well as a kit for carrying out such assays.
    Type: Grant

  • Reagent system and process for adenosine triphosphate monitoring
    Patent number: 7556933
    Abstract: A reagent system comprises a first reagent which includes a high pH phosphate buffer, and a second reagent which includes luciferase, luciferin, a magnesium salt and an enzyme stabilizer. The second reagent has a low pH and a buffer with a pK which is near the optimum pH for activity of luciferase. The reagent system may be used in a process for measuring total adenosine triphosphate (ATP) and/or dissolved extracellular ATP, in a fluid containing microorganisms. The reagent system may also be used in a microbiological remediation or production process.
