Ad-p27mt的聚合酶链反应检测Ad-p27mt转染大肠癌细胞后的p27mt的表达。结果:①用含pShuttle-CMV-hp27mt转化含pAdeasy-1的超感受态BJ5183后,可获得约30%的阳性重组质粒。②聚合酶链反应检测表明重组腺病毒DNA中含有目的基因。重组腺病毒滴度为7.95×1015pfu/L。

The GPA1 gene was obtained via PCR amplification and was cloned in the two-hybrid DNA binding domain vector pGBKT7 The combinant plasmid was designated as pGBKT7-Ga.β-galactosidase assay indicatedthat Got did not have the property of self-activation. After pGBKT7-Ga was transformed to yeast pJ69-4A, we transformed Arabidopsis vegetative tissue two-hybrid cDNA library plasmids to yeast pJ69-4A containing pGBKT7-Ga.

通过PCR扩增得到GPA1基因并将其克隆到双杂交DNA结合域载体pGBKT7中,得到的重组质粒命名为pGBKT7-Gα,β—半乳糖苷酶活性鉴定表明Gα不具有自激活特性,将其转化到酵母菌pJ69-4A中,再以此为受体菌转化拟南芥绿色营养组织cDNA文库质粒。

With the comparition of the two groups, the conclusion can be drawn that the p80 protein expressed by the plasmid pEGFP-P80 cannot cause the detectable depression of activity of PK-15 cells.

结果表明,利用pEGFP-P80 重组表达质粒在PK-15 细胞中表达出的p80 蛋白未对宿主细胞有明显的致病变作用。

The result suggests that Al2O3 nanoparticle can stimulate donor function and thus result in a significant increase in conjugative plasmid dissemination in aquatic environments.

In order to do this, we get equal quantities of plasmid pSCA1-M, pcDNAM and pSCA1 transfected vero cells. After 48 hours, we observed the presence of special green fluorescence in cytolymph in both of pSCA1-M and pcDNAM groups. However, this fluorescence is absent in the negative pSCA1 group.

分别取等量的重组质粒pSCA1-M、常规IBV M基因DNA疫苗质粒pcDNAM、空载体pSCA1转染Veto细胞。48h后经间接免疫荧光试验观察发现,pSCA1-M以及pcDNAM转染组细胞浆均可见特异性亮绿色荧光,pSCA1空载体组无荧光为阴性。

Accordingly, a new plasmid Cm1301 was constructed containing osGP fragment (-197~-56) from the osRACD promoter with the minimal promoter,-90 region of CaMV 35S which confers Gus activity detectably only in roots. In the transgenic plants containing Cm1301, GUS activity was detected mostly in the anther.
