  • Process for stabilizing the content of glycated protein of a sample on a matrix material
    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

  • Stabilized reagent and method for determining creatine kinase
    Patent number: 6413733
    Abstract: A stabilized reagent for the photometric enzymatic determination of creatine kinase (CK) in biological sample material by forming ATP from creatine phosphate and ADP and detecting the ATP formed, containing an organic or inorganic sulphur compound preferably in a submolar amount relative to the added CK activator. A corresponding reagent in a liquid form is stable at 2 to 8° C. for up to 12 months without significant loss of function.
