Abstract

PURPOSE: To obtain a remarkably stabilized urease composition, by incorporating a mixture of urease with a thiol compound, a chelate reagent and an organic dibasic acid or a salt thereof in the composition.
CONSTITUTION: 1.0pt.wt urease is mixed with 0.0001W0.5pt.wt. thiol compound, e.g. glutathione, dithiothreitol or dithioerythritol, 0.01W5.0pts.wt. chelate reagent, e.g. ethylenediaminetetraacetic acid and a salt thereof and nitrilotriacetic acid and a salt thereof and 0.01W100pts.wt. organic dibasic acid, e.g. oxalic acid, malonic acid, malic acid, tartaric acid, maleic acid or fumaric acid, or a salt hereof.
