摘要
用十六烷基-二甲基-乙基-溴化铵(CTAB)法快速高效地从样品中提取了可供分析的基因组DNA,经PCR扩增,鉴定了含有35S启动子和NOS终止子的转基因样品.该方法的灵敏度可达0.1%,并且具有很好的稳定性.
CTAB method was used to extract DNA from the food samples. This method is simple, fast and can make the consistency of DNA higher. It is suitable to extract large quantity DNA. PCR method is used for assaying transgenic component 35S promoter derived from Cauliflower Mosaic Virus and NOS terminator derived from Agrobacterium tumefaciens in foods. The sensitivity can reach 0.1% and the stability is excellent.
