查询词典 research and studies

The different fishes which are employed in the present studies are wild-type salmon, cultured salmon of freshwater and seawater, sea perch and fat greenling. The complete CT gene sequences of salmons are obtained by PCR amplification. The partial CT sequences of sea perch and fat greenling are obtained by in vitro cloning PCR method. Alignment of obtained CT sequences with other fish CT shows that CT appears to be well conserved among the same family. And the relative in taxonomy is far away, the similarity of different fish CTs is low. On the contrary, the closer the relative in taxonomy is, the higher the similarity of different fish CTs is. The sCT is expressed in pGEX-4T-X by recombinant form . We also succeed in the research of sCT expression alone by expression PCR. In addition, sCT antiserum is obtained using GST-sCT as antigen, and the high titer is tested by double immunodiffusion. In the rat bioassay, administration of 50 μg recombinant protein evoked significant hypocalcemia at 1 h after the data are analyzed by t-test.

本文用PCR方法克隆了野生鲑鱼、养殖鲑鱼的降钙素基因，并应用体外克隆PCR的方法首次克隆出鲈鱼、六线鱼降钙素的部分基因序列，通过对克隆的降钙素序列的比较研究，结果显示同一科的鱼降钙素序列保守性较高，同时，根据降钙素的部分氨基酸序列进行了降钙素相似性的比较研究，结果显示在分类学上，分类地位较远的鱼，其降钙素相似性较低，分类地位越接近的鱼，其降钙素相似性越高；我们利用谷胱甘肽S-转移酶(Glutathions S-transferase，GST)融合表达载体pGEX-4T-X对克隆的鲑鱼降钙素基因进行了融合表达研究，应用表达PCR的方法对降钙素基因的独立表达进行了初步的研究探索，并将纯化的融合蛋白作为抗原，获得了高效价的兔抗鲑鱼降钙素免疫血清；生物活性研究表明，大肠杆菌表达的融合蛋白具有显著的降血钙作用。

Its accurate error is lower than the permissible error regulated by the government in feasibility research phrase. Because of the penetrability of its process and normality and objectivity of its results, subjectivities of organizations or individuals can be avoided effectively and different estimators can get almost the same result by using it. Furthermore, its process has stronger persuasiveness than former ones. So it is obvious that the new method is better than former methods and other model predicting methods in similar studies.
