In pot experiments, 6-benzylaminopurine and abscisic acid were brushed onto the ears, upper or lower blades of Echinochloa frumentacea to analyze the regulation of partial changes caused in the balance of endogenous hormone on Na(superscript +), K(superscript +) and free proline at whole plant level.

以盆栽的C4植物－湖南稷子为材料，用6-苄氨基嘌呤和脱落酸定位涂抹湖南枝子的穗、上位和下位叶片，分析了植物体激素平衡的局部改变对整株水平上Na+、K+和游离脯氨酸分配的调节。

Because adenine methylation does not occur endogenously in most eukaryotes, it provides a unique tag to mark protein interaction sites.

由于腺嘌呤甲基化不在大部分的真核细胞中内源性发生，它提供了一个单一的tag来标记蛋白质相互作用位点。

The hypoxanthine/XO reaction in the DMPO-ESR technique was used to correlate the effect on enzyme inhibition and ROS suppression by these coumarin derivatives, and the results showed that esculetin and 4-methylesculetin were the two most potent agents among the tested compounds.

最后以电子自旋共振法，利用 Hypoxanthine/ Xanthine Oxidase反应体系，产生之O2-自由基，去评估香豆素及其衍生物对於黄嘌呤氧化酶活性抑制和自由基清除的能力的整体表现，结果显示esculetin 和 4-methylesculetin具有最佳的活性。

AAⅠ活化后能与腺嘌呤形成AAⅠ-DNA加合物，LC/MS/MS技术能够决速力便准确地检测AAⅠ-DNA加合物。

Methods 2BS cell lines were treated with Tuber Fleeceflower Root serum. The activity of c-myc mRNA was detected by semi-quantitive RT-PCR. A TRAP-ELISA method was used to measure the telomerase activity.

采用含何首乌血清对2BS细胞株进行处理，用黄嘌呤氧化酶法检测SOD活性，RT-PCR检测c-myc mRNA表达，TRAP-ELISA检测端粒酶活性。

After it gets pasteurized all the valuable enzymes in milk are destroyed (lactase for the assimilation of lactose; galactase for the assimilation of galactose; phosphatase for the assimilation of calcium).

但是当我们将脂肪打散成很小的例子时，许多人相信同时会产生一种化学物质称为—黄嘌呤氧化酶这是均质化的牛奶被认为容易造成癌症的原因。

The guanine plus cytosine content mol% of Pseudomonas cocovenenans subsp farinofermantans, Burkholderia gladioli and Burkholderia cocovenenans, which were similar in biochemical characteristics, were determined with Tm values method and HPLC method, and the comparative study of these two methods was discussed.

利用复性速率法和高效液相色谱法对生化性状比较相近的椰毒假单胞菌酵米面亚种、唐菖蒲伯克霍尔德氏菌和椰毒伯克霍尔德氏菌共7个菌株的鸟嘌呤和胞嘧啶摩尔百分含量%进行了测定，并对这2种方法做了对比研究。

Fertilizated eggs of abalone Haliotis discus Hannai were treated with cytochalasin B, cafeine and 6-dimethylaminoparine (6-DMAP) to block polar body Ⅰ, and the separated chromosomes of control and experimental groups were analysed.
