摘要:

摘要: 聚丙烯酰胺凝胶电泳目前已经广泛应用在SSR标记、SNP标记以及遗传图谱的构建等过程中, 但是一直以来凝胶银染方法由于染色时间长、染色步骤繁琐, 使得对于开展大批量的实验研究极为不利。文章通过对常规方法的改良, 建立了一个银染步骤只需要10 min, 整个染胶过程只需约20 min的快速、高效的银染方法。

Abstract:

Abstract: 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.
