| 摘 要： | 以固定化核苷磷酸化酶(EC 2.4.2.1)、黄嘌呤氧化酶(EC 1.2.3.2)与过氧化氢电极构成电流型酶电极,研究了肌苷酶电极分析法的各种分析条件及参数,并与紫外分光光度法对比测定了肌苷片中肌苷含量。酶电极法测定结果与紫外法测定结果之间有较好的一致性。采用酶电极法测定肌苷片中肌苷含量专一性高、成本低、分析速度快。

| Abstract: | We employed an amperometric enzyme electrode constituted by nucleoside phosporylase,xanthine oxidase and a hydrogen peroxide electrode to determine inosine in inosine tables.The correlation coefficient of such enzyme electrode method and ultraviolet method was 0.8844,better consistency.Experiment shows that this enzyme electrode method has such positives as high specialization,low costs and rapid analysis. |
