The peptide bond has partial double bond character and is nearly always in the trans configuration.

半胱氨酸残基之间共价二硫键的位置也包括在一级结构之中。

Our results showed that 1, 8-Naphthyl imide could improve the properties of natural oligonucleotide in resisting nuclease and binding the targeted sequence by covalently linkage at the end of oligonucleotide. Moreover, our results also showed that the antigene oligonucleotide could specifically cleave the targeted double DNA sequence by modification of naphthyl imide at the 3'end of oligonucleotide.

体外结果表明萘二酰亚胺对寡核苷酸的共价修饰可以提高天然寡核苷酸抗核酸酶降解能力，提高寡核苷酸与靶序列结合的稳定性以及使寡核苷酸具有选择性结合和切断靶DNA的功能。

Yesterday afternoon,"Daily Economic News" Reporter董秘call the company to do, staff members made it clear that, 30 million commitment to the performance of the company there is no relation between Shanghai in 2007 were the highest price momentum once close to 59 yuan/Unit, and after 10 to send 10, ex-dividend price of 29.5 yuan/Unit, Therefore, the major shareholders to determine the price of 30 yuan commitments.

昨天下午，"每日经济新闻"记者致电公司董秘这样做，工作人员明确表示，3000万的承诺，公司业绩之间没有关系，2007年上海人的最高价格的势头一度接近59元/股，经过10送10，昔日的二十九点五元红利价/单位，因此，大股东确定承诺的30元人民币的价格。

We coupled the IgG of monoclonal antibody N34 specific to UK and the Fab of monoclonal antibody SZ-51 specific to the membrane protein GMP-140 of activated platelet. The bispecific antibody (N34 SZ-51) is able to bind UK and plasma-clot simutaneously. It enhanced plasma clot lysis 5 fold by HUK whereas it enhanced plasma clot lysis 38 times by LUK. UK in association with the bispecific antibody didn't decrease the concentration of fibrinogen in the assay supernatants.

利用抗体介导使纤溶酶原激活剂定向到血栓表面，可大大提高其纤溶作用，我们用双功能团试剂将抗尿激酶的单克隆抗体N34的IgG和抗活化血小板膜蛋白GMP-l40的单抗SZ-5l的Fab片段通过二硫键共价偶联，合成的双专一性抗体（N34-SZ-51）既具有血栓亲和性也具有尿激酶亲和性，从而增加了尿激酶对血栓的专一性，使高分子量尿激酶溶栓率提高了5倍，使低分子量尿激酶溶栓率提高了38倍之多，且不影响血浆中纤维蛋白原的含量。

A fish dealer named Tsai, who has been going crazy lately as the wholesale price of milkfish has plummeted to about NT$28, says with exasperation: Milkfish used to be a very expensive item, which people only got when recovering from an operation or after having a baby.

最近为了虱目鱼的批价一斤已经降到二十八元左右的成本价而伤透脑筋的蔡姓业者感慨地表示：「过去虱目鱼是很高贵的东西，开刀和坐月子的人才吃的。

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。

His coat is rated at 20 yuan.

他的大衣值价二十元。

Every value is to be set according to the sanctuary shekel, twenty gerahs to the shekel.
