  • Gel-forming insert for electrophoresis gels
    Patent number: 6136172
    Abstract: Electrophoresis gels are formed using a gel-forming insert having a beveled edge which results in loading sites having a beveled bottom surface. The gel forming insert can have a continuous beveled edge across the entire width of the gel, in which case a special loading insert is used which matches the bevel of the gel. Alternatively, the gel forming insert may be formed with a plurality of fingers with beveled ends, each finger defining a well in the gel. In one form of the gel-forming insert, the fingers are formed from a soft, flexible polymer such as silicone applied on a rigid support.
