    • 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.
    • 一种进行电泳实验的装置,包括用于接收电泳缓冲液的容器和用于保持浸入缓冲液中用于分离分离电泳样品的凝胶含有盒的缓冲芯组件。 缓冲芯组件限定了用于电泳缓冲液的流动路径,其可以通过热交换器和泵循环,以实现缓冲器和盒表面之间的受控热交换,从而将凝胶和电泳过程保持在期望的温度下均匀 在凝胶盒的表面上。 缓冲芯组件还具有用于接收与凝胶接触的第二可充电缓冲液的上孔,以便在与第一缓冲液结合的电泳上在凝胶上施加电场。 该井与第一缓冲液隔离,以防止缓冲液混合并降低电气短路的风险。

    • 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.
    • 用于切割凝胶的设备和方法包括凝胶切割管和网状材料。 网状材料延伸穿过管的端部。 为了使用切碎装置对凝胶进行细分,将凝胶放置在打孔管中的网状材料上,在离心机中将切细管,网状材料和凝胶纺丝,迫使凝胶通过网状材料,使凝胶细分 变成大致均匀的较小碎片。 网状材料可以以嵌套管的形式固定到管。 嵌套管嵌套在回收容器的开口内。 网状材料可以与嵌套管中的条状多孔膜串联放置。 将嵌套管和回收容器离心通过使凝胶通过网状材料将凝胶材料细分成碎片。 凝胶随后落在膜上,并且可以在膜上处理以提取或以其它方式处理凝胶材料中的分析物。
