Amplification of Trat gene of E.coli in poultry and preparation of trat-dig gene probe

鸡大肠杆菌traT基因的扩增及TraT-DIG探针制备

According to the trat of plane cam , the plane camCAD / CAPP / CAM integration system is studied and developed .

根据平面凸轮类零件的特点，本文对凸轮集成系统的体系结构进行了分析和研究。

The core of traT gene , pathogenicity concerned , was amplified by using artificial synthesis primers and pure extracted plasmid of pathogenic E. coli strain as template .

以致病性E.coli的质粒为模板，用人工合成引物扩增出致病性相关的traT基因核心部分；

Methods The telomerase activity in aging mice tissue before and after treatment with P. sibiricum were measured by TRAT microtiter plate hybridization method and tissue MDA was measured by modified TBA fluorescence method .

方法采用端粒重复扩增微孔板杂交法检测衰老动物组织黄精治疗前后的端粒酶活性；采用改良TBA荧光法测定组织丙二醛（MDA）含量。
