    摘要： The invention provides populations of molecules that are prepared as, or treated to become, homogeneous for one or more molecular characteristics. In an aspect, the invention relates to molecular weight standards that may be used to determine the molecular weight or apparent molecular weight of uncharacterized molecules, such as proteins and nucleic acids, as well as in other applications. In one aspect, the molecular weight standards are pre-stained.

    摘要： An apparatus and method for mincing a gel includes a gel mincing tube and a mesh material. The mesh material extends across the end of the tube. To subdivide a gel using the mincing apparatus, a gel is placed upon the mesh material in the mincing tube, the mincing tube, mesh material and the gel are spun in a centrifuge, forcing the gel through the mesh material so that the gel is subdivided into generally uniform smaller fragments. The mesh material may be secured to a tube in the form of a nesting tube. The nesting tube nests within the opening of a recovery vessel. The mesh material may be placed in series with a conditionally porous membrane in the nesting tube. Centrifuging the nesting tube and the recovery vessel subdivides gel material into fragments by forcing the gel through the mesh material. The gel subsequently falls upon the membrane, and may be treated on the membrane to extract or otherwise treat analytes in the gel material.

    摘要： An apparatus of conducting electrophoresis experiments including a container for receiving an electrophoresis buffer and a buffer core assembly for holding gel-containing cassettes that are immersed in the buffer for molecular separation of an electrophoresis sample. The buffer core assembly defines a flow path for the electrophoresis buffer which can be circulated by means of a heat exchanger and a pump to effect controlled heat exchange between the buffer and the cassette surfaces thereby maintaining the gel and the electrophoresis process at a desirable temperature uniformly over the surfaces of the gel cassette. The buffer core assembly also has upper well for receiving a second electrically chargeable buffer in contact with the gel so as to impose an electric field on the gel for the electrophoresis in conjunction with the first buffer. The well is isolated from the first buffer to prevent mixing of the buffers and to reduce the risk of an electrical short.
