| 摘 要： | 对转基因玉米深加工产品中DNA的提取技术进行了研究。首先,通过经典CTAB法、CTAB初步改良法、CTAB有效改良法和煮沸法等4种方法提取了玉米片和爆米花中的DNA;其次,用琼脂糖电泳检测法将DNA进行了分离;再次,用紫外可见分光光度法检测出4种方法提取的DNA的纯度。结果表明,4种方法中的CTAB有效改良法提取DNA的完整性、纯度更好。

| Abstract: | In this paper,we researched the extraction technology of DNA from transgenic maize. First,extracted DNA from corn flakes and popcorn by classical CTAB、 Preliminary improvemented CTAB、 improved CTAB method and the boiling method;Second,we separated DNA by agarose gel electrophoresis. Third,we checked the purity of the DNA. The experimental results showed that improved CTAB was the best method in the integrality and purity. |
