  • Assay of micro-organisms in cell cultures
    Patent number: 6951723
    Abstract: Micro-organisms which over-produce ATPase, especially mycoplasmas in a sample of a cell culture, are detected by making use of the ATPase activity to convert cellular or externally added ATP to ADP. The decrease in ATP externally added or the increase or absolute level of ADP produced from cellular ATP can then be detected or measured. For example, if a reagent such as phosphenol pyruvate/pyruvate kinase is added to convert that ADP back to ATP, the resulting high level of ATP can be detected bioluminescently using the reaction: Luciferin+luciferase enzyme+ATP?hv+products.
