Construct of EGFP expression system containing 5'UTR of β-actin gene for black carp was transferred into zygotes of mud loach and COS-7 cells and the results showed that 5'UTR of β-actin gene for black carp could be used as the promoter of the"all-fish"transgene.

基于鲤科鱼类Beta-肌动蛋白基因序列，采用长片段PCR技术，克隆了青鱼β-actin基因DNA片段，并构建了青鱼β-actin基因5'启动调控区绿色荧光蛋白表达载体，通过显微注射泥鳅胚胎和COS-7细胞转染实验，证明了所克隆的青鱼β-actin基因5'启动调控区具有启动调控功能，并用之来构建&全鱼&基因的启动子部分。

Objective Establishment of a hybridoma cell line secreting a monoclonal antibody to facilitate iˉdentification of human tissue kallikrein（KLK1gene,hK1protein）.Methods Mice were immunized with E.coli-exˉpressed GST-hK1fusion protein and their spleen cells were fused with SP2/0myeloblastoma cells.Specificity of the monoclonal antibody was shown by Western blotting and by immunofluorescence.Results The monoclonal antibody reacted specifically to E.coli-expressed hK1and with the KLK1cDNA-transfected COS-1cells.

目的 将人组织激肽释放酶（基因命名 KLK1，酶命名为hK1）cDNA克隆入肠杆菌表达质粒，以重组菌表达的GST-hK1融合蛋白免疫小鼠，获得了分泌hK1特异单克隆抗体的杂交瘤细胞株方法将KLK1cDNA克隆入真核表达质粒，用获得的重组质粒转染COS-1细胞，经间接免疫荧光试验证明，上述单克隆抗体能与转染细胞发生特异反应。

Transcription/translation assay and transient transfection of COS-7 cells with a cDNA encoding Sparus aurata lier GK showed the functionality of the enzyme in itro.

转录和翻译水平的分析，以及用金头鲷肝脏GK的cDNA转染COS－7细胞都表现出GK在体外的活性。

The results show that although the amount of organic sulfur did not change remarkably, the H2S evolved from the oxidized sample decreased, COS and SO2 evolved increased significantly. This indicated that the aliphatic sulphides were selectively oxidized to sulphoxide and sulphone.

结果表明，空气和HNO3氧化后，尽管煤中有机硫总量变化不大，但煤中H2S的释放量有所下降，而COS和SO2的生成量明显增加，这说明氧化作用使得煤中弱的有机硫变成S=O和SO2结构。

In these results there are some new findings:(1) when there is not initial geometry defect, multi-waves phenomena still exist and are presented in low orders in vibrative mode shape;(2) of the total vibrative mode shapes of empty tanks there is a type of vibrative mode shapes with the same waves and different directions cos (nθ+φ〓,φ〓≠0 ;(3) the total vibrative mode shape of empty tanks compose of axial symmetry and non-axial symmetry ones corresponding to upright and oblique vibrative mode shape matrices respectively.

最后对空储液罐的特征值问题进行了多达近万自由度的计算分析，得到了一些成果，其中有新的发现：（1）空储液罐的多波现象在无初始几何缺陷时依然存在，而且出现在低阶振型中；（2）在罐的总体振型中存在有同波异向振型（cos，φ〓≠0）；（3）罐类的总体振型由轴对称和非轴对称振型组成，并存在相应的正、斜振型矩阵。

You can also try to open a little more features, such as animation around, young people are loyal consumer groups, small investment, quick recovery, but also the twenty-first century, pioneering the development of key state industries, like the well-known brand AA Anime International Anime is not only novel and practical The animation peripheral products, as well as creative DIY fashion personality animation production, animation COS pictorial photography and fine animation clothing props, these are precisely the most popular among the young and the pursuit of things.

还可以尝试开个比较特色一点的，比如动漫周边，年轻人是忠实的消费群体，投资小回收快，也是二十一世纪国家重点倡导发展行业，像知名动漫品牌AA国际动漫，不仅有新奇实用的动漫周边产品，还有时尚个性的动漫DIY创意制作，动漫COS摄影写真和精美的动漫服装道具，这些正是现在年轻人最青睐和追求的东西。

RESULTS The recombinant human prolidase expressed in COS-7 cells catalyzed the hydrolysis of organophosphorous compound soman as well as the hydrolysis of dipeptide Gly-Pro.
