    • A preparative electrophoresis device having a pair of spaced apart plates, a pre-cast electrophoretic gel between the plates, and a semipermeable membrane sealably connected to ends of the plates to define with the plates a collection channel for receiving molecules that have traveled through the gel. Also disclosed are close spacing (less than 2.0 mm) of the plates, an inlet tube and an outlet tube connected to the two plates and communicating with opposite ends of the collection channel, an elongated divider between the plates to divide the gel into a purification region and an indicating region that is not as wide as the purification region and receives marker molecules of known molecular weight to indicate the location in the indicating region of molecules of interest, and pumping electrophoretic buffer into the collection channel at the same rate that it is pumped out.
    • 一种制备型电泳装置,其具有一对间隔开的板,在板之间的预制电泳凝胶,以及半透膜,其可密封地连接到板的端部,以与板一起限定用于接收已经穿过凝胶的分子的收集通道 。 还公开了板的紧密间距(小于2.0mm),连接到两个板并与收集通道的相对端连通的入口管和出口管,在板之间的细长分隔器,以将凝胶分成纯化 区域和指示区域,其不如纯化区域那么宽,并且接收已知分子量的标记分子以指示感兴趣的分子的指示区域中的位置,并以相同的速率将电泳缓冲液泵送到收集通道中 抽出来
