Polyacrylamide gel electrophoresis is widely applied in the SSR, SNP markers analysis and the construction of genetic map. It is disadvantage to use conventional silver-stained methods in experiment due to taking a very long time and having fussy steps. In this paper, a silver-stained method of DNA in PAGE gel was improved. The improved method is rapid banding which only takes about 20 min, and the high definition picture was obtained.
聚丙烯酰胺凝胶电泳广泛应用于SSR、SNP标记分析及遗传图谱构建。传统的银染方法在实验中存在耗时较长且步骤繁琐的缺点。本文对聚丙烯酰胺凝胶中DNA的银染方法进行了改进。改进后的方法显带快速,仅需约20分钟,且能获得高清晰度的图片。
