  • Method for detection of protein on polyacrylamide gels using a counter-dye composition and counter-dye composition for the same
    Patent number: 6277643
    Abstract: The present invention relates to a method for detection of protein using a counter-dye composition, on polyaciylamide gels, and the counter-dye composition for detection of protein on polyacrylamide gels. More specifically, the present invention relates to a method for detection of protein in a high sensitivity on polyacrylamide gels in a rapid and simple manner, comprising the step of staining the polyacrylamide gels with a counter-dye composition containing an acidic organic dye and a basic organic dye, and the counter-dye composition for detection of protein on polyacrylamide gels.
    Type: Grant

  • 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.
