- 摘要:
- 以不夜城芦荟的幼嫩叶片为试材,分别采用SDS法和CTAB法以及简化的CTAB法对基因组DNA进行提取,并利用紫外分光光度计和琼脂糖凝胶电泳法检测其DNA的浓度、纯度及质量,以期筛选不夜城芦荟基因组DNA提取的最合适方法。结果表明:对比不夜城芦荟基因组DNA提取的3种方法,无论从提取浓度还是纯度上来看,SDS法均明显优于其它方法。
- Abstract:
- Taking the young leaves of Aloe nobilis as material,SDS and CTAB and simplified CTAB method were used to extract genomic DNA from Aloe nobilis,and the content and the purity of DNA were detected by the methods UV spectrophotometer and agarose gel electrophoresis,to compare various methods of extraction of the quality and efficiency,and find out the most appropriate method.The results showed that compared three kinds of DNA extraction methods of Aloe nobilis genome,either from the extract concentration or purity,SDS was significantly better than the other methods.
