查询词典 cloning

To get more factors associated with erythropoiesis in K562 cells, modified differential display reverse transcription polymerase chain reaction method was applied to identify genes with differential expression in uninduced and hemin-induced K562 cells. Remarkable differential ESTs were firstly selected for cloning, sequencing and analyzed with bioinformatics methods.

为了进一步获得分化过程中相关基因表达的信息，我们应用改良的差异显示RT-PCR技术，分析K562细胞在Hemin诱导的红系分化前后的基因表达变化，获得红系分化相关基因的线索，进而确定在红系分化中起重要作用的基因，并研究它们的作用机制。

This is one case where even people unnerved by cloning might see it as not the worst option.

从这个例子，即使对克隆技术不感冒的人们也能发现基因克隆不是最坏的选择。

Owing to the variability of HVR1, the method to check anti-HVR1 antibodies need to cloning and expressing the gene of HVR1 of every sera and that poses some problem. For example, it needs lots of time and money, and the sample must come from viremic patients. It is urgent to acquire a broadly cross-reactivity HVR1 antigen to check the antiHVR1 Ab in the sera of HCV infected patients by ELISA.

由于HVR1的高变性，因此要想测定血清中抗HVR1水平，通常要克隆表达待测血清中的HVR1基因，但该方法时间长、费用高，并仅对HCV、RNA阳性血清适用，所以急需一种具有极高交叉反应性的HVR1抗原，才可通过ELISA对病人的HVR1抗体进行检测。

In recent years, with the development of the molecular cloning technology, genetic engineering and bioinformatics, the study of vitellin gene will provide a new method to biological control of pests.

近几年，随着分子克隆技术、基因工程手段和生物信息学的发展，对卵黄蛋白基因的研究将为寻找害虫生物防治提供新途径。

Further studies showed some DH plants could generate two or more than two stems in which wrinkledness mutant and wild types except for the leaf wrinkledness, therefore they were the better materials for studying the wrinkledness characteristic. The finding is useful in studying, locating and cloning the wrinkledness gene linked to leaf mutants of Brassica allosextuple CGMCC № 2553 DH lines in the future.

进一步研究发现，在同一DH再生植株上常常会萌发出皱缩和野生型的2个或多个分枝，由于皱缩和野生型除了叶片皱缩性状不同外，其他性状完全相同，因此叶片突变体和野生型是研究叶片皱缩性状的理想材料，有利于进一步研究皱缩基因的遗传，定位、克隆叶片皱缩相关基因。

Based on the cDNA sequence of the zfh -1 gene in Drosophila , a novel human homolog located on chromosome 9 was found by computer cloning method.

利用果蝇心脏发育基因 zfh-1的 c DNA序列和计算机克隆方法，在 9号染色体上发现了一个新的人类同源基因。

If the UK approves the cloning, it would be a world first.

如果英国同意进行克隆，这将是世界上的首例。

The way of promoter cloning is important for constricting gene engineering vectors and expressing the aim proteins.

启动子的克隆对于构建基因工程载体，表达目的蛋白有着重要的意义。

放射性标记单克隆抗体有直接法和用双功能联结剂的间接法。

Yet while Little Nicky, who was delivered two weeks ago, frolics in his new home, the kitten's creation and sale has reignited fierce ethical and scientific debate over cloning technology, which is rapidly advancing.

这家公司还表示，他们计划在明年5月之前&生产&出世界上第一只克隆狗。但据报道，这种做法已经开始遭到反对动物克隆人士的抗议。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。

The factory affiliated to the Group primarily manufactures multiple-purpose pincers, baking kits, knives, scissors, kitchenware, gardening tools and beauty care kits as well as other hardware tools, the annual production value of which reaches US$ 30 million dollars.
