    摘要: Beansprucht werden neue 1-Naphtholphthaleinmonophosphate sowie ein Verfahren zu deren Herstellung. Hierzu werden Naphtholphthaleine mit Phosphorverbindungen in Gegenwart einer organischen Base umgesetzt und gegebenenfalls bromiert.
    Die neuen Verbindungen werden von alkalischen Phosphatasen gespalten und eignen sich demnach als Substrate für die Bestimmung der Aktivität von alkalischen Phosphatasen. Die als Spaltprodukte entstehenden 1-Naphtholphthalein-Derivate können photometrisch bestimmt werden.

    摘要: A labile, organic reagent which is unstable in aqueous media and stable in a non-aqueous media is stabilized by dissolving the organic reagent in a water-miscible, organic solvent which is liquid at room temperature and which is nondegradatively reactive with the organic reagent to form a solution of the organic reagent in the organic solvent. At least 1 percent of an inert, high surface area particulate dessicant is added to the solution for entrapping water with the dessicant so that the residual water content of the solution is below about 0.5 percent. The dessieant can be removed from the solution before seating it. More than one organic reagent can be added to the solvent, and a solubilizing agent for the organic reagent can be used.

    摘要: The subject invention provides a method for analyzing the metabolic activity in cells by improving the retention of a detectable reporter molecule only in intact cells where a particular enzyme is present. In particular, improved retention results from a two part process involving conjugation of haloalkyl-substituted derivatives of a reporter molecule with intracellular cysteine-containing peptides while unblocking the reporter molecule. The method for analyzing metabolic activity of cells involves the use of a substrate having the form XR-REPORTER-BLOCK wherein -BLOCK is a group selected to be removable by action of a specific analyte, to give REPORTER spectral properties different from those of the substrate, -REPORTER- is a molecule that, when no longer bound to BLOCK by a BLOCK-REPORTER bond, has spectral properties different from those of the substrate, and XR- is a haloalkyl moiety that can covalently react with an intracellular thiol (Z-S-H) to form a thioether conjugate (Z-S-R-). After the substrate enters the cells, the analyte removes BLOCK to make REPORTER detectable by the change in spectral properties, and the haloalkyl XR reacts with the intracellular thiol to form the thioether conjugate inside the cells, which is well-retained in the cells.
