More Information
Summary:The biosensor has an electrode system for electrochemically measuring 1,5-anhydroglucitol and a reagent layer formed on said electrode system. The reagent layer contains (1) an enzyme for measuring 1,5-anhydroglucitol, (2) phenothiazines, (3) a stabilizer selected from a group of compounds comprising metal salts, organic acids, and amino acids, and (4) an acidic polymer compound as an optional ingredient, and the biosensor has excellent storage stability and can electrochemically measure 1,5-anhydroglucitol unaffected by the hematocrit contained in a whole blood sample. L'invention concerne un biocapteur qui comporte un système d'électrodes pour mesurer par voie électrochimique le 1,5-anhydroglucitol et une couche réactive formée sur ledit système d'électrodes. La couche réactive contient (1) une enzyme permettant de mesurer le 1,5-anhydroglucitol, (2) des phénotiazines, (3) un stabilisant choisi parmi un groupe de composés comprenant les sels métalliques, les acides organiques et les acides aminés, et (4) un composé polymère acide en tant qu'ingrédient éventuel. Le biocapteur présente une excellente stabilité au stockage et peut mesurer par voie électrochimique le 1,5-anhydroglucitol insensible à l'hématocrite contenu dans un échantillon de sang total.
