    • The guanase activity in body fluids such as blood serum can be rapidly and accurately assayed by (I) decomposing guanine with the guanase in the specimen to xanthine and ammonia at pH 7-9, preferably at pH 8, (II) decomposing the xanthine formed by former step I with xanthine oxidase to uric acid and hydrogen peroxide, (III) reacting the reactant solution of the former step II with 3-methyl-2-benzothiazolinonehydrazone, an aniline derivative such as N,N-di-lower-alkylaniline and peroxidase, and finally measuring the optical absorption of the reactant solution of the step III at 570-600 nm. The all steps can be completed within 15 minutes. Therefore, this assay is adoptable for automatic assay of guanase on usual clinically available automatic analyzers.
    • 通过(I)将样品中的鸟嘌呤分解为黄嘌呤和氨,pH7-9,优选pH8,(II)分解形成的黄嘌呤的鸟嘌呤,可快速准确地测定体液如血清中的鸟苷酸活性 通过前一步骤I将黄嘌呤氧化酶与尿酸和过氧化氢反应,(III)使前一步骤II的反应物溶液与3-甲基-2-苯并噻唑酮腙,苯胺衍生物如N,N-二低级烷基苯胺和 过氧化物酶,最后在570-600nm测量步骤III的反应物溶液的光吸收。 所有步骤可在15分钟内完成。 因此,该测定法可用于通常临床可用的自动分析仪上的鸟苷酸的自动测定。
