  • Patent number: 7078480
    Abstract: The invention concerns a method for stabilizing the content of glycated protein in a sample on a matrix material, which is characterized in that the matrix material is impregnated with boric acid buffer with a pH which is larger or equal to 10.5 or a transition metal salt as well as an appropriate matrix material, an element for collecting, transporting and storing sample material to be analysed with such a matrix material and a system containing such an element and a sealable covering.
    Type: Grant
    Filed: March 28, 2003
    Date of Patent: July 18, 2006
    Assignee: Roche Diagnostics GmbH
    Inventors: Rolf Nagel, Jürgen Mistele

  • Patent number: 5374546
    Abstract: The invention concerns a process for stabilizing the enzyme 1-methylhydantoinase (NMHase) which is characterized in that the NMHase is treated with divalent metal ions, a nucleoside triphosphate and a complexing agent which complexes these divalent metal ions. In addition the invention concerns the use of an enzyme stabilized in this way in a method for the determination of an analyte in which 1-methylhydantoin is converted, as well as a corresponding reagent.
