carboxyl terminus meaning in English

羧基端

To investigate the secondary structure of this gene , we found it has a transmembrane region near the n - terminus , followed by a proline - rich conserved region , and it has a conserved haemachrome binding region about 60 aa away from carboxyl terminus
分析氨基酸序列的二级结构发现基因n -端具有跨膜的疏水序列，其后具有富含脯氨酸保守区，在距离羧基端60个氨基酸处具有高度保守的血红素结合域。
As well as in eukaryocyte ( hepg2 and cos - 7 ) , then detect their antigenity as a basis study and explore of the choice of immunogen for preventive and therapeutic vaccines of hepatitis b . methods : the gene fragments coding 152aa ( si ) and 124aa ( s2 ) of the carboxyl terminus of hbsag were amplified by pcr from plasmid pecob6 with a pair of primers containing different endonuclease sites and were cloned into multiple cloning sites of plasmid pbks ( + )
为乙型肝炎的预防和治疗性疫苗免疫原的选择进行初步的研究和探讨。方法：本研究利用聚合酶链反应( pcr ) ，通过设计带有不同酶切位点的一对引物，从质粒pecob6特异性扩增hbsag蛋白羧基末端152个氨基酸( s1 )和124个氨基酸( s2 )的基因片段，分别将二者克隆到质粒pbks ( + )的多克隆位点，筛选重组克隆。
