| 摘 要： | 为了快速、低成本获得高质量的芝麻基因组DNA，本实验在借鉴其他作物DNA常规提取方法基础上，简化了提取步骤，减少了试剂用量，DNA经琼脂糖电泳检测无拖尾，且OD260 /OD280在1.8～2.0之间，表明质量、纯度均较高，摸索了一套芝麻DNA高效提取方法；在常规变性聚丙烯酰胺凝胶（PAGE）银染程序基础上进行改良，减少了固定环节和试剂用量，缩短了染色和显影时间等，优化建立了芝麻PAGE快速银染方法。

| Abstract: | In order to obtain high-quality sesame genomic DNA rapidly and economically for molecular experiments, an efficient method suitable for DNA extraction of sesame was explored, referred methods in other crops, the procedure was simplified and the cost was reduced, DNA were detected by agarose electrophoresis and no trailing phenomenon was found, their OD 260 /OD 280 values were all between 1.8-2.0, indicating that qualities of DNA were good and high purity. Afterwards, in order to further improve the efficiency of molecular marker experiments, a rapid and effective silver staining procedure for polyacrylamide gels was established, by improving the traditional silver staining methods, eliding the fixation, reducing cost and controlling the staining and imaging time. |
