目的 对碱裂解法提取质粒DNA中主要试剂的作用进行研究。

To prove that the cloned DNA fragment can express tryptopanase,a new plasmid pET28C-TnaA , in which the cloned DNA fragment was located downstream of T7 promoter on pET28c was constructed and transformed into host BL21(DE3),a BL21 lysogen of bacteriophage DE3 in which the only promoter known to direct transcription of the T7 RNA polymerase gene is the lacuvS promoter ,which is inducible by IPTG.

为了证明质粒上的基因能表达出有活性的色氨酸酶,将这个DNA片段克隆到PET28c质粒的BamHI和HindⅢ位点上,使该片段受T7 RNA聚合酶的启动子控制,然后转化噬菌体DE3的溶源菌BL21(DE3)。

Objective To explore the effects of N -Has gene over expression on malignantly transformed human bronchial epithelial cell induced by anti-benzo pyrene-trans-7,8 dihydrodiol-9,10-epoxide (16HBE-T) using small hairpin RNA. Methods The recombinant plasmid pGPU6/GFP/Neo-NRas-566 including N-Has shHNA was transfected to 16HBE-T cells.

Methods Twenty-four wells in four 6-well culture plates in which HUVECs were growing were medially divided into 2 groups with 12 holes in each group: TFPI group and empty plasmid group.

方法将长有HUVEC的4个6孔培养板中24孔平均分为2组,即TFPI转染组和空载体转染组,每组12孔。

Coli XL-1 strain, purposed cassette recombination plasmids pNB0098-K and pNB0097-K were constructed, in which the purposed gene was linked with plasmid pUC18, and the marker gene kanamycin was inserted in the purposed gene. The linear cassette DNA fragment was mixed in the medium of cultured competent cells of meningococcus BT878. The function of the purposed gene was inhibited by the homologous replace of casstte gene.
