The results showed a modification method of Yoo was the best method for assaying α-amylase. The experiments ascertained the best conditions for assaying α-amylase and indicated the conversion coefficient of five kinds of enzyme activity unit. 通过比较研究,认为Yoo改良法是α&淀粉酶活力测定的最佳方法,并确定了各方法不同活力单位之间的相互换算关系。
The result shows that the optimal effecting dose of Tannase is 4.0U/g and the total Catechins of tea soup goes down and the light transmittance increases constantly, along with the increase of enzyme unit and effecting time. 结果表明,单宁酶最佳作用剂量为4.0U/g;在一定范围内,随着酶剂量的增加,茶汤中酯型儿茶素的总量在不断减少,茶汤的透光率随着酯型儿茶素的减少在不断增大;
Methods To determine the urinary γ-GT and creatinine on Olympus 2700 auto-matic biochemistry analyzer. The enzyme activity unit was indicated as U/ g@ Cr. 方法在Olympus2700全自动生化分析仪检测尿γ-GT和尿肌酐,并用U/g·Cr的单位表示酶活性单位。
The level of chlamydia pneumonia antibody was expressed with the enzyme-linked immune unit. 标本的肺炎衣原体抗体水平用酶联免疫单位表示。
Under the optimization condition of culture, the enzyme activity can reach 6 unit/ ml within 48 hours. 用最佳培养基和培养条件,48小时酶活性最高可达6u/ml。
As a new type of carrier-free immobilized enzyme, cross-linked enzyme aggregates ( CLEAs) with characteristics of simple preparation, high activity per unit volume and good stability has been extensively used in many fields. 作为一类新型的无载体固定化酶,交联酶聚集体以其制备方法简单、单位体积酶活高以及稳定性好等受到广泛的关注。
