摘要:
The present invention relates to oxidoreductase apoenzyme variants which are enzymatically inactive but have coenzyme-binding properties. Further, the present invention relates to DNA sequences encoding these oxidoreductase apoenzyme variants, expression vectors containing such DNA sequences and the use of these oxidoreductase apoenzyme variants in diagnostic applications.
摘要:
A method for producing a polymer layer on a transparent support. A photopolymerizable liquid composition is applied to the support. The photopolymerizable liquid composition is irradiated through the support such that polymerization of the liquid composition starts at the surface of the support and ends at a predetermined distance over the surface of the support. Only partial polymerization of the liquid composition takes place. A polymer layer with a predetermined thickness is formed on the support wherein the predetermined thickness is less than the thickness of the photopolymerizable liquid composition. The remaining photopolymerizable liquid composition is removed from the entire polymer layer.

The invention relates to processes and devices for detecting an analyte in a sample by fluorescence measurement of a fluorophore, wherein the detection medium which contains a fluorophore or a precursor of the fluorophore is admixed with an absorber whose absorbance spectrum superimposes the fluorescence excitation range of the fluorophore. The system consisting of the fluorophore and the absorber, which is produced in the detection medium, has an altered effective fluorescence excitation range with an altered fluorescence excitation maximum. Illumination with fluorescence excitation light can take place within the range of this altered excitation maximum. The measured signal obtained from determining fluorescence emission exhibits only low dependence on the wavelength of the excitation light.

An analytical system for detecting an analyte in a body fluid comprises a disposable integrated puncturing and analyzing element and a reusable analytical system. The integrated element includes a puncturing element having a tip for generating a puncture wound in a body part and an elongated flat test strip having a top side and a bottom side. The integrated element is held in a holder such that, in a sample application position of the test strip, the top side of the test strip is facing upward. A sample application area for manual application of a drop exiting from the puncture wound of the body part is provided on the top side of the test strip such that, in the sample application position, the drop is applied to the sample application area from directly above.
摘要:
The invention concerns a reagent system for the so-called on-board control of analytical elements, in particular test strips, containing an organic N-oxide or a nitroso compound. The invention also concerns analytical elements containing a reagent system for a detection reaction and a reagent system for an on-board control. Furthermore, the invention concerns a method for checking analytical elements in which a reagent system for an on-board control is examined optically or electrochemically with the aid of a measuring instrument for changes which could indicate a stress of the analytical element.
