  Bis-diazo, triaryl and aryldiazo-N-arylphenazonium quencher moieties, substituted with electron-withdrawing and electron-donating substituents which induce polarity in the delocalized aryl/diazo ring systems, are useful as labels when attached to biomolecules such as polynucleotides, nucleosides, nucleotides and polypeptides. The quencher moieties are non-fluorescent and accept energy transfer from fluorescent reporter labels by any energy-transfer mechanism, such as FRET. Fluorescence quencher compositions are useful in preparing quencher labeled biomolecules for various molecular biology assays based on fluorescence detection.

  双重重氮基团、三芳基和芳基重氮-N-芳基苯唑啉猝灭基团，通过在离域芳基/重氮环系统中引入电子受体和电子供体取代基，可以作为标签附加到生物分子上，如多核苷酸、核苷、核苷酸和多肽。这些猝灭基团是非荧光的，可以通过任何能量转移机制（例如FRET）从荧光报告标签接受能量转移。荧光猝灭剂组合物在制备标记生物分子的过程中非常有用，用于各种基于荧光检测的分子生物学测定。

  A test strip having the capability of separating blood cells from whole blood, wherein it has a porous reagent layer comprising beads, an inorganic gel and a reagent that causes a detectable reaction with a substance to be detected, and a substrate that supports the reagent layer, wherein the beads are adhered to each other with the inorganic gel, and interstices are formed between the beads to trap a solid. The test strip can thus be used for separating blood cells from a whole blood including blood cells and plasma and detecting a substance to be detected, such as glucose, contained in plasma. The use of the test strip allows the measurement of a substance to be detected even by measurement of a transmitted light, the exhibition of good oxygen permeability, and thus can be used for measuring a substance to be detected with improved accuracy.

  The present invention provides a biosensor that can prevent a mediator from being affected by oxygen, thereby allowing an analyte in a sample solution to be measured rapidly and easily with high accuracy. The biosensor can be produced by providing a substrate having electrodes, applying a solvent containing a mediator, a surfactant, a buffer, and a layered inorganic compound to surfaces of the electrodes to form an inorganic gel layer for preventing natural oxidation of the mediator, and forming an enzyme reagent layer containing an oxidoreductase on the inorganic gel layer. In this biosensor, due to the inorganic gel layer, the mediator having been reduced by the reaction between an analyte and the oxidoreductase can be measured electrochemically, without being reoxidized by dissolved oxygen or the like.
