  • Method for detection of DNA on polymer gels using a counter-dye composition and counter-dye composition for the same
    Patent number: 6228655
    Abstract: The present invention relates to a method for detection of DNA using a counter-dye composition containing two dyes of which electric charges are contrary to each other, on polymer gels, and the counter-dye composition for detection of DNA on polymer gels. More specifically, the present invention relates to a method for detection of DNA in a high sensitivity on polymer gels in a rapid, simple and safe manner, comprising the steps of staining the polymer gels with a counter-dye composition containing a cationic dye and an anionic dye and then macroscopically observing the gel without radiation of ultraviolet ray, and the counter-dye composition for detection of DNA on polymer gels.
