查询词典 affinity

Upon binding ATP or a nonhydrolyzable analog such as AMPPNP, RecA undergoes an allosteric transition into a high-affinity DNA-binding form. When RecA combines with dsDNA to form RecA-dsDNA nucleofiliment, it can unwind dsDNA and change the dsDNA structure.

在ATP或其类似物的辅助下，RecA可以直接与双股DNA结合而形成核丝，并将双股DNA加以解螺旋，并改变双股DNA的结构。

On the other hand, co-immunoprecipitation assay revealed that the DM mutant seems to have a higher affinity than the Wt protein for both Puma and Noxa.

此外由共同免疫沉淀实验中发现DM hMcl-1与Puma 和Noxa间的亲和力是比Wt hMcl-1好的。

The recombinant protein was purified by Ni-NTA affinity chromatography and gel filtration chromatography. The inbred C57BL/6 strains and outbred KM strains of mice were subcutaneously immunized with the protein formulated by either adjuvant ISA720 or aluminium hydroxide.

表达产物通过Ni-NTA亲和层析和凝胶过滤层析方法纯化，再分别与ISA720和Al3佐剂乳化后，免疫C57BL/6和昆明小鼠，通过尾蚴膜反应和ELISA反应检测特异性抗体。

ELISA and immunofluorescence assays showed that ER had strong affinity for A431 and A549 cells that overexpress EGFR.

ELISA检测及细胞免疫荧光显示融合蛋白与纯EGFR抗原的相对亲和力为8.0×10~(-9)M，对EGFR高表达的肿瘤细胞的亲和力明显高于低表达的正常细胞。

Methods The type Ⅳ pilin protein PILE was purified by HisTrapTM HP affinity columns ,then the purified protein was examined by SDS-PAGE and Western blot.

使用HisTrapTM HP亲和层析柱纯化Ⅳ型菌毛蛋白PILE，并对纯化蛋白进行SDS-PAGE和Westernblot鉴定。

The synergism ratios of piperonyl butoxide to alpha-cypermethrin in these three strains were similar(about 20-fold), which suggested metabolic detoxification probably confers about 20-fold inherent resistance in the B-type whitefly, as PBO is a mixed function oxygenase and esterase inhibitor and glutathione S-transferase is not affinity to resistance in B. tabaci. The synergism ratio of triphenyl phosphate to alpha-cypermethrin in the NJ strain was 12-fold, which implied the synergism of PBO in the B-type whitefly is mainly due to inhibiting esterase activity.

增效试验表明PBO对这三个品系的增效作用均为20倍左右，因为在烟粉虱中PBO即是多功能氧化酶抑制剂，也是酯酶抑制剂，而谷胱甘肽S-转移酶与抗性无关，因此推断代谢酶在B型烟粉虱对高效氯氰菊酯的抗性发展中起到的相对作用可能为20倍左右，而且这种抗性是B型烟粉虱天生的；TPP对NJ品系的增效作用为12倍，说明PBO增效作用主要是由于抑制酯酶而引起的，即代谢抗性大部分由酯酶所贡献。

As the chitosan is an alkaline polyose, it can be degradated in conjuction with polylactic acid and can suppress that polylactic acid generates pH pulses on environment in degradation process, increasing the cell affinity of the surface of polylactic acid material.

由于壳聚糖是一种碱性多糖，它与聚乳酸同时降解，还可以对聚乳酸降解过程中对环境产生pH脉冲作用起到抑制作用，提高了聚乳酸材料表面的细胞亲和性。

The mutant △RSD-9 K141D was subcloned into the pGEX-6p-1 expression vector and the △RSD-9 protein was purified by GST affinity chromatography and digested by Prescission Protease to cut the GST domain. Next, to further verify the intracellular interaction of RSD-9/△RSD-9 and rtSH3p13 proteins, laser confocalization study and co-immunoprecipitation method were used.

随后，我们又运用蛋白质在细胞内的荧光共定位实验和免疫共沉淀实验，在细胞内相互作用水平上，证明了RSD-9蛋白/△RSD-9蛋白都与rtSH3p13蛋白在胞内相互作用。

Because the atomic affinity energy of Ca-O and Be-O is lower than Mg-O,The Ca and Be aggregating on the surface of liquid Mg will priorly combined with O,forming compact oxides of Ca,Be and alloys of elements,which prevent Mg alloys from burning.

由于Ca，Be与氧的原子亲和能低于镁与氧的亲和能，聚集在液体表面的Ca，Be将优先与氧结合，生成致密的镁与合金元素的混合氧化物，阻止镁合金燃烧。

They probably bind to all proteins, and disrupt some of them, but for some reason their affinity for proteolytic and respiration-related enzymes is particularly obvious.

他们可能绑定到所有的蛋白质，破坏他们中的一些，但出于某种原因，他们的亲和力为蛋白质和呼吸相关酶活性的，特别是显而易见的。

I go to school at night.

我是上上学。

Clear Tip Nasal Aspirator: A soft time and gentle suction action makes removing excess mucus easy.

鼻吸明确提示：一个柔软的时间和温柔吸力行动使消除过剩的粘液容易。
