摘要: 随着转基因产品的大规模商业化和我国大规模进口油菜籽,有效管控存在的风险显得非常必要和有意义,试验研究了质粒标准分子pMs8的研制过程,包括质粒分子的构建、纯度分析、特异性检测、均匀性检验、稳定性考察、定值。结果表明,该质粒分子标准物质的内源基因和外源基因的均匀性良好,没有扩增出所选的其他特异性基因,短期稳定性在14 d(处理温度大于25 ℃)发生显著变化,长期稳定性大于6个月,两种方法对外源基因拷贝数的定值结果相近,因此,pMs8是有准确量值的质粒标准分子。可替代性研究结果表明,其可替代基因组作为转基因油菜Ms8定量的阳性标准。

Abstract: With the commercialization of genetically modified organism (GMO) and large scale of rapeseed imported to China, it was essential to manage and control existing risks. In this paper, genetically modified rapeseed Ms8 was prepared including analysis on preparation, purity, homogeneity, stability and certified value. The results showed that the homogeneity of endogenous gene and exogenous gene of reference molecule was well. No other selective specific gene had been amplified by PCR. Short term stability of reference molecule was obviously changed which were stored at room temperature for 14 days, and long term stability of reference molecule was more than 6 months. The certified value of exogenous gene of reference molecule determined by microspectrophotometric method and digital PCR method was similar. Thus, pMs8 can be used as reference material, and the reference molecule is suitable for the rapid identification of modified rapeseed Ms8 in unknown samples.

Key words: transgenic rapeseed, digital PCR, reference plasmid, Ms8
