Improvement of the silver-stained technique of polyacrylamide gel electrophoresis

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.
