查询词典 DNA

Virus removal efficiency is determined by the real time PCR and inactivation efficiency is determined by cell-based infectivity assay.Enveloped DNA virus removal and inactivation: Real time PCR indicated that method based on gold magnetic particles coupled with antiserum has shown great superiority on virus removal. Cell-based infectivity assay indicate pasteurism has shown superiority on virus inactivation.

对两种指示病毒分别进行巴氏灭毒和偶联抗血清金磁颗粒处理，实时荧光定量PCR检测核酸变化确定病毒的去除效率，同时进行病毒的细胞感染力实验确定病毒的灭活效率，结果显示：在对DNA有包膜病毒的去除能力上，金磁颗粒法明显优于普通的巴氏灭活法；在对DNA有包膜病毒灭活能力上，巴氏法明显优于金磁颗粒法。

Using the method of fluorescence labeling, a new DNA algorithm of the perfect matching problem based surface is presented in this paper.

基于最佳匹配问题的问题解空间，采用荧光标记的策略，给出了一种新的最佳匹配问题的DNA表面计算模型，该模型首先将问题解空间的DNA分子固定在固体载体上，然后通过进行相应的生化反应来求得最佳匹配问题的所有解。

These ingredients includes epidermal growth factor, hepatocyte growth factor, dimethyl sulfoxide, phenobarbital sodium and all trans-retinoic acid. We isolate and culture primary 10-weeks-old human fetal hepatocytes, observe hepatocytes form and its function markers. Inoculate hepatocytes with HBV Dane particles to observe if HBV susceptibility of fetal hepatocytes can be induced in vitro. To detect HBV covalently closed circular DNA within hepatocytes, we improve the existent PCR method.

基于上述假设，我们设计了10种培养条件，在自行设计的无血清培养基中添加不同的细胞分化诱导物，包括表皮生长因子、肝细胞生长因子、二甲基亚砜、苯巴比妥钠、全反式维甲酸等，分离孕10周龄人胎肝细胞进行原代培养，观测肝细胞形态及功能指标变化，并定时给予HBV感染，观察能否在体外诱导胎肝细胞出现HBV易感性；为检测肝细胞内HBV共价闭合环状DNA(covalently closed circular DNA，cccDNA)，我们改进了现有的PCR检测法。

At the same time, through the atom ratio of chlorine to phosphor, the hybridization efficiency of the DNA probes anchored on silver film was calculated to be 90.81%, which was largely higher than those probes affixed on conventional glass substrate (30.63%).

与此同时，通过氯原子与磷原子的个数比得到了银膜DNA芯片上杂交效率为90.81%，高于常规玻璃载体基因芯片的杂交效率（30.63%），说明银膜DNA芯片能够实现碱基序列正错配的分析，自组装化学镀银膜是一种应用前景较好的基因芯片载体材料。

DNaseⅠ,preferentially attacking double-stranded DNA to produce oligonucleotides with 5'-phosphoryl and 3'-hydroxy termini, is considered to play a major role in digestion of dietary DNA.

目前已发现DNA酶Ⅰ存在6种编码蛋白的基因多态性、单核苷酸多态性和内含子4的可变串联重复序列。

In vitro SUMO modification of the BRCA1/BARD1 heterodimer greatly increases its ligase activity, identifying it as a SUMO-regulated ubiquitin ligase. Further, PIAS SUMO ligases are required for complete accumulation of double-stranded DNA damage-repair proteins subsequent to RNF8 accrual, and for proficient double-strand break repair.

Galenty等人发现，两个连接酶（PIAS1 和 PIAS4）在DNA双链断裂处将各种不同的SUMO蛋白添加到DNA修复蛋白上，而SUMO蛋白则是泛素随后修饰这些蛋白中的其中一些所必需的。

Discovered the piezoelectricity DNA sensor to examines the specificDNA sequence is one new effective method, in research and so on ingene examination will be able to play the vital role.

发现压电DNA传感器对检测特定DNA序列是一种新的有效方法，在基因检测等研究中将能发挥重要作用。

Genomic DNAs were then purified from these cells and treated with piperidine for chemical cleavage. Adjust treated DNA concentration to 0.4μg/μl.

细胞裂解后，用常规方法制备基因组DNA，而后进行吡啶化学法裂解，调整裂解后的DNA浓度为0.4μg/μl。

BALB/c from Chongqing had polymorphisms at 7 sites and displayed polymorphisms at the D10Mit180 site comparing with BALB/c of Shanghai. DNA fingerprints of Wistar rats were studied with JL-2 multilocus prober and southern hybridization.
