| 摘要 |
The present invention relates to a method for enhancing stability of a composition comprising soluble glucose dehydrogenase (GDH). Soluble GDH is preferably FAD-dependent GDH derived from filamentous fungus, and the best effect is observed in FAD-GDH derived from A. oryzae or FAD-GDH derived from A. terreus. According to the invention, in a composition comprising soluble glucose dehydrogenase (GDH), stability of GDH can be enhanced by coexisting the enzyme with one or more compounds selected from amino acids and sugars which are not substrate of the enzyme, thus expected to enhancing a measurement accuracy of glucose.
